The Avdira archaeological site, situated at Bouloustra cape, comprises the northern and southern precincts along with the ancient city’s acropolis and cemeteries. These areas, dating back to the Archaic, Classical, and Hellenistic eras, exhibit remnants such as sections of walls, ancient buildings predating the Clazomenia city of Asia Minor from the 7th century BC, parts of Tiion’s wall dating from the 6th-5th century BC, and a boathouse from the same era at the northeastern harbor. Additionally, ruins of a sanctuary dedicated to Dimitra and Kori from the 6th-4th century BC and a Hellenistic cemetery are present. The primary excavated section near the current port showcases the western part of the city’s southern precinct, featuring walls, gate towers, roads, and houses. Noteworthy structures include imperial-era houses, the Christian cemetery of Polystylo, and opulent bath ruins with distinctive features like an oval hall and stairway leading to hypocausts.

Despite these accessible areas, numerous excavations within proximity remain incomplete. The acropolis, located at the southern end, preserves a section of the ancient wall, while the western coastline reveals remnants of the harbor’s breakwater. The second port city, situated to the east, boasts a jetty and warehouses. While private residences, shops, walls, and Byzantine tombs at Polystylo offer insights into daily life, the identification of public buildings remains elusive. The theater, positioned between the northern and southern walls on a hillside, is too deteriorated for visitation.
