Seek the Roman city beneath Agia Petra only after confirming whether the excavation is open to visitors
The Roman settlement on Agia Petra hill explains why Didymoteicho's story begins before its castle. Excavations have exposed architecture and notable mosaics associated with Plotinopolis, traditionally linked to Trajan and named for his wife Plotina. See finds and interpretation in the Byzantine Museum first; the hill is more meaningful once its relationship to the later town is clear.
This is an archaeological work site, not an always-open park. Ask the museum or local archaeological service whether a visit is possible that day and where lawful access begins. Do not cross a fence, move protective covering or follow an unverified map pin through private ground. Exposed areas offer little shade. Closed shoes, water and strict attention to staff directions are essential if access is granted.
