Eretria is not simply a modern seaside town of Evia island. Beneath today’s streets, along the shoreline and between contemporary houses, unfolds one of the most complete ancient cities in Greece.
The archaeological site of Eretria allows visitors to walk through neighborhoods, agoras, sanctuaries, theaters, and gymnasia, gaining a clear understanding of how an important city functioned and evolved from the Geometric to the Roman period.
It is an archaeological walk where history is not isolated from the landscape, but seamlessly integrated into the modern experience of the place.
How the Ancient City of Eretria Was Organized
Walking through modern Eretria, the remains of the ancient city appear scattered beneath the present-day urban fabric, revealing an extensive and well-organized settlement that once stretched from the coastline up to the hill of the acropolis.
Ancient Eretria was protected by a strong fortification wall approximately 4 kilometers long, which began at the acropolis and extended down to the harbor, clearly defining the boundaries of the city.
Within the walls, the urban space was organized into eastern, western, and northern districts, connected by two main road axes. One axis linked the western and eastern gates of the city, while the second led south toward the Sanctuary of Apollo Daphnephoros and the Agora — the heart of public life.
Archaeological Museum of Eretria – The Starting Point of the Walk
The Archaeological Museum of Eretria houses important finds from systematic excavations in the city and the wider region, covering a broad chronological span from the Early Bronze Age to the Late Roman period. A visit to the museum is the ideal starting point for understanding the history and development of ancient Eretria.
The centerpiece of the collection is the western pediment from the Sanctuary of Apollo Daphnephoros, depicting the dramatic abduction of the Amazon queen Antiope by Theseus. Of particular interest are also the funerary finds from the Geometric cemetery of Lefkandi, as well as objects from prehistoric settlements such as Xeropolis, Amarynthos, and Magoula.
The museum also displays significant finds from the Sanctuary of Artemis Amarysia at Amarynthos, one of the most important archaeological discoveries of recent decades in Evia. The sanctuary was identified in the area of Palaiochoria of Amarynthos, and the finds recovered span from the Geometric to the Hellenistic period.
Excavations carried out by the Swiss School of Archaeology in collaboration with the Ephorate of Antiquities of Evia revealed more than 600 objects associated with the cult of the goddess Artemis, many of which are presented in the museum’s permanent and temporary exhibitions.
Among them stand out stamped roof tiles bearing the name “Artemis,” dedicatory inscriptions of the Hellenistic period mentioning Artemis, Apollo, and Leto, terracotta and bronze figurines, including Centaurs and rare clay plaques, as well as personal objects and weapons such as gold and silver jewelry, scarab-type seals, bronze vessels, helmets, and shields.
A particularly rare find is an ivory head with Egyptian features, offering valuable evidence of the wider cultural contacts of the region.
The museum is located on Ancient Theatre Avenue 1, in direct proximity to the archaeological site, and perfectly complements the exploration of the monuments of the ancient city.
The Western Quarter and Its Luxurious Residences
Leaving the museum and following the ancient road, the visitor enters the Western Quarter, an area that experienced significant development during the 4th century BC and includes some of the best-preserved private residences in central Greece.
House II, covering an area of approximately 1,260 sq m, is a characteristic example of an elite urban residence of ancient Eretria. It features a monumental entrance, a large peristyle courtyard, banquet rooms (andrones), storage areas, a secondary courtyard, and private living quarters with kitchen and bath. Three rooms connected to the house had independent access from the street and most likely functioned as shops rented to merchants.
A short distance away stands House IV, organized around a triangular courtyard and including banquet rooms, private quarters, a kitchen, and a bath. Part of the building was occupied by a workshop with storage jars, a wine press, and an olive press, revealing the coexistence of domestic life and productive activity within the same complex.
The Western Gate – The Main Entrance of Ancient Eretria
At the end of the Western Quarter lies the Western Gate, the most important entrance to ancient Eretria from the direction of Chalkida. The gate was formed by a courtyard flanked by two rectangular towers built in polygonal masonry, while remains of the ancient road surface and elements of the door-locking system are still visible.
The Western Gate underwent successive modifications from the 6th to the 2nd century BC. In its final phase, it was dismantled and replaced by a large tower designed to house war machines, probably of Macedonian construction dating to the late 3rd century BC.
The Heroon – Memory and Cult
A short distance back from the Western Gate lies the Heroon, a monument dated to the late 8th or early 7th century BC. This was a burial area for prominent individuals, whose cremated remains were found inside bronze cauldrons.
The area appears to have functioned as a place of cult dedicated to one of the city’s “founding heroes.” The numerous ceramic finds and terracotta figurines discovered in the deposits of the area attest to the long-term ritual use of the site from the Archaic period onward.
Ancient Theatre of Eretria
Leaving the Western Quarter and passing through an opening in the enclosure, the visitor comes face to face with the Theatre of ancient Eretria, one of the most impressive landmarks along the route.
Built on an artificial embankment, the theatre dominates the landscape not only because of its scale but also because of its position. It stands at the heart of a major building program developed at the foot of the acropolis.
The choice of its location is explained within the context of an extensive urban program of the second half of the 4th century BC, which did not focus on a single monument but on an entire ensemble of public spaces: the Theatre, the Sanctuary of Dionysus, the Gymnasium with its covered passage, and the Stadium. This is precisely what makes the experience of Eretria feel so “alive” for the visitor: you do not simply see ruins, but you understand how a city consciously invested in public life and its urban image.
The Ancient Theatre of Eretria was originally constructed in the 5th century BC and reached its greatest prominence during the 4th century BC, a period when the city maintained intense political, social, and cultural activity. Dedicated to Dionysus, it served as a central venue for theatrical performances and religious ceremonies.
The theatre follows the characteristic layout of ancient Greek theatres, with a circular orchestra, a stage building, and a cavea partially carved into the natural slope of the hillside. Its capacity is estimated at several thousand spectators, underlining its importance as a space for public gathering and cultural expression in ancient Eretria.
In the wider area of the theatre, the foundations of a temple and an altar associated with Dionysian rituals have been identified. These elements demonstrate that the theatre functioned not only as a place of entertainment but also as a religious center, where theatrical art was closely connected to the worship of the god.
The Ancient Theatre of Eretria is considered one of the most significant monuments of the city and forms an integral part of the extensive archaeological site, offering valuable insight into the public life, ritual practices, and cultural identity of ancient Eretria.
The Acropolis
Directly behind the Theatre, the fortification wall of the ancient city still rises prominently today, enclosing the Acropolis, a point where the experience of Eretria shifts level. From the exploration of the “lower” urban landscape, the visitor moves into a space that carries much older layers of human presence.
On the plateau of the summit, the remains of the earliest prehistoric settlement were uncovered, dating to the Late/Final Neolithic and the Middle Bronze Age, along with the ruins of a sanctuary dedicated to Athena. This gives the visitor a rare sense of continuity: the same hill preserves traces of life from prehistory through to the historical periods.
Along the edges of the Acropolis, references are also made to a Hellenistic cistern and two Thesmophoria, elements that open up a second level of interpretation. This is not merely a fortified position, but a landscape shaped by worship, infrastructure, storage, and ritual practices.
The Gymnasium
Continuing along the route, the Gymnasium of Eretria stands out for a feature highlighted by the archaeological sources as particularly rare: it includes two peristyle courtyards. This architectural type is uncommon in Greece and was likely adopted to allow the simultaneous training of two different age groups.
Even more striking for the visitor is the fact that the Gymnasium was not simply a place for physical exercise. It was equipped with bathing facilities, including basins and floor-installed tubs for foot baths, as well as a tholos that functioned as a steam room.
These installations are presented as precursors to the Roman baths with hypocaust systems that were constructed in the 2nd century AD, approximately 100 meters away, highlighting the continuity of public bathing traditions in Eretria.
Sebasteion – Temple of Imperial Cult
After experiencing the city in its Classical and Hellenistic phases, the visitor encounters a space that marks its transformation during the Roman period. At the intersection of the two most important roads of the ancient city, the urban center during the early centuries AD, a small temple of imperial cult, known as the Sebasteion, was constructed, alongside shops and workshops.
The House of the Mosaics – Luxury in Hellenistic Eretria
In the central district of the ancient city, among public buildings and major road axes, luxurious residences developed during the Hellenistic period, reflecting the wealth and social standing of their owners.
The most impressive of these is the House of the Mosaics, one of the best-preserved examples of a private residence from the period.
The mosaic floors of the house are now protected by a shelter and form a key point of interest for visitors. The central mosaic depicts scenes from the mythical battle between the Arimaspians and the Griffins, a subject linked to the world of fantasy and exotic mythology.
In the mosaic at the entrance of the same banquet room, Thetis, the mother of Achilles, is shown carrying the hero’s armor while riding a hippocamp.
The choice of themes, combined with the high quality of execution, clearly indicates that the house belonged to an individual of high social and economic status. For today’s visitor, the House of the Mosaics functions as a “window” into the private life of Hellenistic Eretria, revealing how everyday living was intertwined with aesthetics, myth, and the display of prestige.
The Roman Baths – Everyday Life in the Imperial Period
A short distance further on, near a key crossroads of the ancient city, a medium-sized Roman public bath complex was uncovered, built shortly after the middle of the 2nd century AD. This monument clearly reflects Eretria’s transition into the Roman period and the adoption of new forms of public life.
The baths follow the typical layout of Roman bathing facilities. Visitors would first enter a vestibule leading to a large changing room equipped with benches and a mosaic floor. From there, the route continued to the frigidarium, with a cold-water pool, and then to a sequence of heated rooms operating with an underfloor hypocaust system.
These spaces included the tepidarium, the laconicum, and the caldarium, the latter equipped with two hot-water basins. Adjacent to the changing rooms was a small peristyle courtyard, which functioned as a space for relaxation and social interaction.
According to the archaeological evidence, the monument is expected to be further enhanced and made fully accessible to visitors, offering a comprehensive picture of everyday Roman life in Eretria.
The Quarter of the Panathenaic Amphorae – A Neighborhood with 14 Centuries of Life
In a central area of the settlement developed the so-called Quarter of the Panathenaic Amphorae, one of the most stratified areas of ancient Eretria. This district experienced nearly continuous occupation for approximately fourteen centuries, making it exceptionally important for understanding the long-term evolution of the city.
On both sides of the ancient main road, houses and shops dating to the Classical and Hellenistic periods have been uncovered. To the east of the street, a deposit containing nine Panathenaic amphorae was discovered, the find that gave the quarter its name.
During the Roman imperial period, workshops were built over the earlier houses, along with a sanctuary with a monumental entrance, the dedication of which remains unknown. Excavation of the earliest layers revealed that as early as the 8th century BC, houses and graves coexisted in the same area, near an ancient riverbed.
The Sanctuary of Apollo Daphnephoros – Religion and Ritual within the Urban Fabric
Leaving the area of the House of the Mosaics and the Roman baths and continuing southward, the visitor follows one of the main north–south axes of ancient Eretria. Before reaching the Agora, the Sanctuary of Apollo Daphnephoros appears on the right.
Today, what is primarily visible are the foundations of the Doric temple, dated to the late 6th century BC. These foundations consist of large blocks of local gray limestone, while two column drums indicate the position of the temple’s peristyle.
In the northeastern corner of the archaeological area, the remains of a distinct sacrificial space can be seen, separate from the cult area of Apollo. This zone yielded a large number of ritual vessels, including tall-necked jugs, miniature hydriae, and small objects that functioned as votive offerings.
The finds indicate that the goddess Artemis was also worshipped in this area, alongside Apollo, highlighting the complex and multi-layered religious life of ancient Eretria.
Agora and Tholos – The Center of Public Life
Continuing southward, the visitor reaches the Agora, the true heart of the ancient city. The earliest human activity in the area dates to the Early Bronze Age (3000–2000 BC); however, continuous occupation was not possible before the 6th century BC due to fluctuations in water levels.
The open space of the Agora was surrounded by four stoas, while at its center stands a circular building with a surrounding colonnade: the Tholos, constructed in the 5th century BC. Today, the Tholos is the most clearly visible architectural remain of the Agora.
The best-known structure of the Agora is the Eastern Stoa, built in the last quarter of the 6th century BC. It measured approximately 120 meters in length and 9 meters in width, featuring a colonnade on the western side and 22 shops on the eastern side, where foodstuffs, locally produced pottery, and imported goods from Attica were sold.
After its destruction by fire, the stoa was repaired and later replaced by a new structure of greater width. Although the architectural remains of the stoas are no longer visible, the Tholos remains a key reference point. Its exact function, whether a public building or a sanctuary, has not yet been definitively established.
Baths in the Center of the Ancient City
Continuing the walk from the Agora and the Tholos, the visitor encounters, in the center of today’s Eretria and near the point that connects the ancient harbor with the modern seaside area, the remains of Roman-period baths, dated from the late 2nd century AD to the mid-3rd century AD.
These public installations, with their characteristic spaces for hot and cold bathing, attest to the existence of organized public hygiene and social life in the city during the Roman period.
Today, the baths remain visible within the archaeological site and are connected to the axis that linked the harbor with the upper parts of the city, offering visitors a clear and coherent picture of the ancient urban layout.
The Iseion – Egyptian Cults in Evia
The Iseion of Eretria is one of the earliest and few fully excavated sanctuaries of Egyptian deities in Greece. According to an inscription found on the site, the cult was established in the late 4th century BC by merchants who arrived from Egypt.
The sanctuary consisted of an open courtyard surrounded by stoas, with the temple and its cult statue located at the center. Today, only the plastered base of the statue survives. During a modification in the 2nd century BC, a mosaic floor decorated with two swans was added in front of the temple entrance, one of the most distinctive features of the site.
The Iseion clearly reflects the cosmopolitan character of ancient Eretria and its commercial and cultural connections with the wider Mediterranean world.
Palaestra – Athletic Life in Ancient Eretria
After visiting the Iseion and as the walk continues toward the southern parts of the archaeological site, the visitor encounters the remains of the Southern Palaestra of ancient Eretria. This was a public complex used for gymnastic activities, physical training and athletic education, and it played a central role in the social and educational life of the city.
The palaestra is located in the southeastern district of the city, near the Sanctuary of Isis and the fortification walls. It features a large square courtyard surrounded by stoas and a platform with colonnades, elements that reveal the organized architectural design of the complex.
The palaestra was first uncovered in 1917, and archaeological research resumed more than a century later, in 2018, bringing to light important structural remains and occupation layers. These findings confirm that the palaestra was a key center of public and athletic life in ancient Eretria.
To the northwest of the palaestra, a small rectangular space has been identified which, according to epigraphic evidence, was dedicated to the cult of Eileithyia, the goddess who protected childbirth and children.
Investigative trenches in this small sanctuary revealed a well, inside which approximately one hundred small kotylai were discovered. These vessels date to the last quarter of the 4th century BC or the early 3rd century BC, offering valuable insights into the ritual practices of the late Classical and early Hellenistic periods in Eretria.
The Sanctuary of Artemis Amarysia at Amarynthos
A short distance from Eretria, near Amarynthos, one of the most important sanctuaries of ancient Evia comes to light: the Sanctuary of Artemis Amarysia. The site lies at the foothills of the Paleochora hill, below the area known as the Paleochurches, in a landscape that still preserves a strong sense of antiquity.
Systematic excavations in recent years have revealed a monumental Archaic temple of the 7th century BC, approximately 34 meters long, a characteristic hekatompedon (“hundred-foot”) temple, a type associated with major sanctuaries of the same period in the Greek world.
Its apsidal ground plan is a rare architectural feature, while its construction with mud-bricks set on strong stone foundations reflects the particular conditions of the terrain in the area.
One of the most striking aspects of the sanctuary is that sacrifices were performed inside the temple. Hearths and altars were identified within the cella, with thick layers of ash and carbonized bones attesting to the long ritual use of the space.
This practice distinguishes the Sanctuary of Artemis Amarysia from many other Greek sanctuaries, where sacrifices usually took place at outdoor altars.
Excavations also brought to light rich votive offerings: vessels, weapons, jewelry, and objects made from precious materials, including exotic finds such as an ivory head with Egyptian features. These discoveries reveal the wide-ranging connections of Evia with the broader Mediterranean world and highlight the importance of the sanctuary beyond a purely local context.
Beneath the levels of the Archaic temple, traces of even earlier cult activity were uncovered, including building remains from the 9th and 8th centuries BC, as well as finds dating back to the Late Bronze Age. This continuity indicates that the site held a sacred character already from prehistoric times.
Today, a significant number of finds from the Sanctuary of Artemis Amarysia are displayed in the Archaeological Museum of Eretria, allowing visitors to directly connect the city with this major pan-Evian sanctuary of Artemis.
A visit to the site is an ideal extension of the archaeological walk in Eretria and meaningfully completes the picture of the religious and political life of ancient Evia.
