Methoni Castle - one of the most important fortress complexes in Greece - was built after 1209 by the Venetians, who at the time were occupying the area and were seeking to fortify the towns from piracy and rivals seeking to overtake their territories. It was the Venetians who began to build the castle, while during its occupation by the Franks and Ottomans, it unavoidably underwent their alterations.

The castle reached its great prime during the 1st Venetian Rule, between the 13th and the 15th century, while its final decline came about around 1828, when its inhabitants were transferred outside the walls, leaving it to ruin.

The Castle of Methoni covers an area of approximately 93,000 square metres and is divided into two parts. The south part is taken up by the city, which is surrounded by a simple wall, while the city’s fort lies at its northern part, with exterior fortification owing to its defensive purpose. The castle is separated from the land by a ditch and can be reached by a stone bridge with 14 arches.
