Monemvasia is a captivating castle town set on a tiny Peloponnese island, carved into a massive rock. The town is named for its singular entry, which was initially by boat (now via a short causeway). These days, a modern town named Gefyra on the mainland is incorporated into the town’s jurisdiction too. The medieval town’s sublime architecture, pretty cobbled streets, and spectacular castle-top views are the primary drawcard for most visitors, allowing an atmospheric peek into ancient times. History enthusiasts will enjoy a visit to the beautiful Byzantine Agia Sofia, which takes in jaw-dropping vistas, and the fascinating artefacts of the Monemvasia Archaeological Collection, housed in a former temple. Gorgeous beaches, exquisite hiking trails, some wonderful boutiques, and plenty of top-of-the-range restaurants add appeal.
