Nauplion, Greece

Modern compared to the rest of the Peloponnese, Nauplion was briefly Greece's capital before it was moved to Athens in 1834. With its neoclassical buildings and relaxed atmosphere, the city is immensely charming. If you feel energetic, climb the steps to the Venetian fortress of Palamidi for a commanding view of Nauplion. More leisurely options include sunbathing on the beaches and visiting the Peloponnesian Folklore Foundation. For ancient history, venture the short distance to Corinth, which is rich in Roman-built ruins, or visit the archaic Greek ruins at Mycenae and the classic amphitheater at Epidaurus.
