Ethnographic Museum

Scrappy ruin of a Byzantine church, though the chapel vault is still roofed and has frescoes.

Bastion overlooking the harbour, first built in the 8th century BC by Hellenistic immigrants from Miletus, but extended and repaired several times, for instance in the 14th century when the Genoese fortified the entire city. From 1887 to 1997 it housed a high security prison, so it features in the works of a dozen Turkish writers whose seditious publications got them slammed in here. You can look around and climb to the rooftop cafe for views. Otherwise not much here, plans for a cultural centre have come to nothing; perhaps it could be an escape room?
