About Monemvasia

Monemvasia's lower town crowds onto the seaward side of a giant rock, its lanes, churches and walls reached through one gate and linked to the mainland by a causeway. The upper town climbs toward a ruined citadel with the best views, and the fortress beaches and the Mani peninsula fill the days. May, June and September are the best months; summer is hot, and winter is quiet with a handful of guesthouses open.
