Constructed in the 3rd century BC, atop what’s now Filerimos Hill, 10km southwest of Rhodes Town, the Doric city of Ialysos was repeatedly conquered thereafter. The resultant hotchpotch of Doric, Byzantine and medieval remains is now barely intelligible to casual visitors. Stairs from the entrance lead to the ruined foundations of the Temple of Athena Ialysia and the peaceful restored 14th-century Chapel of Agios Georgios. Follow the path left from the entrance to reach another 12th-century chapel, filled with frescoes.
