With an acropolis and powerful fortifications, the ancient city of Troezen was located west of today’s town. Although a large part of the old city was lost when its buildings were razed to make room for new construction, excavations still provided many valuable artefacts, currently on display at the archaeological museums of Poros and Athens.

Pausanias, who visited Troezen in the second century AC, provides much information about the city in the Roman era, especially its temples and fortifications. To the east and west of the city were Troezen’s cemeteries, which revealed interesting finds from the early Geometrical era in the 10th century BC until the Hellenistic period. Artefacts found in the tombs indicate that many local copper workshops served the needs of this secluded agricultural community.
