The castle of Androusa is located about 20 kilometers from Kalamata and was built by the Prince of Achaia and Baron of Kalamata William II Villardouino sometime after 1250.
This long-suffering castle passed into many different hands and today only the ruins of its callus are preserved, such as a series of walls with a length of up to 500 meters and a width of about 1.5m, as well as the cannons and the watchtower as well as four of its towers: one circular, two four-sided and one pentagonal.
Today it is used for various cultural events.
The area is freely accessible at any time of the day, there is no ticket and it is easily accessible.
