Nafplio is a town in the Peloponnese, the capital of Argolida and the main port of the eastern Peloponnese. It is one of the most picturesque cities in the country, and it was the capital of the Greek state during the period 1828 - 1833. It has been characterized as a traditional settlement.

Nafplio is known for Bourtzi, a small fort built on an island in the harbor, Palamidi, a Venetian fortress that dominates the city, Acronafplia, a Venetian fortress on the homonymous peninsula, and the place of murder of John Kapodistrias.

Nafplio is a popular destination for the inhabitants of Attica and the Peloponnese, as it is a bit distant from both areas. The most beautiful buildings of the city are the Armansberg House (residence of the regent of Greece Armansberg) and the archaeological museum at Syntagma Square. In the city there is also an annex of the National Gallery.
