The Peloponnese is a large peninsula in southern Greece, separated from the mainland by the Corinth Canal and connected by the Isthmus of Corinth. It is one of the most historically rich regions in the world, home to four UNESCO World Heritage Sites — Ancient Olympia, Mycenae and Tiryns, Epidaurus, and Mystras — as well as the medieval castle-town of Monemvasia and the dramatic Mani Peninsula. The region blends Bronze Age citadels, classical temples, Byzantine ghost towns, Venetian fortresses, and rugged Mediterranean coastline into a single destination that rewards slow travel.
Historical timeline
Key moments that shaped Peloponnese.

Neolithic habitation at Diros Caves

Battle of Thermopylae — Spartan 300
Spartan King Leonidas leads 300 Spartans against Xerxes' Persian army. Though defeated, the stand became a defining legend of Greek resistance and gave birth to the ideal of martial sacrifice.

Peloponnesian War — Sparta defeats Athens
Sparta (with Corinthian support) defeats Athens in the Peloponnesian War. The Peloponnese League becomes the dominant Greek power, though Spartan hegemony proves short-lived.

Roman conquest — Corinth destroyed
Rome destroys Corinth, massacring or enslaving its population. The Peloponnese becomes the Roman province of Achaea. Caesar refounds Corinth as a Roman colony in 44 BC.

Ottoman conquest of the Peloponnese
The Ottomans take Mystras in 1460, ending Byzantine rule. The Mani Peninsula resists through clan autonomy. Venice holds coastal towns until 1715. Greek language and Orthodox faith survive under Ottoman rule.

Greek War of Independence
The Greek Revolution begins in the Peloponnese on 25 March 1821. The Maniots and Argolida revolt early. The 1827 Battle of Navarino — Anglo-French-Russian fleets destroy the Ottoman-Egyptian fleet in Pylos Bay — effectively secures independence.

Nafplio — First Capital of Modern Greece
Nafplio serves as the first capital of the Greek state. President Ioannis Kapodistrias, assassinated in St. Spyridon church in 1831, is buried here. The capital moves to Athens in 1834.
