The construction of the Medieval Castle of Livadia probably started during the later antiquity or the early Middle Age. It was completed by the Catalans who occupied Livadia in 1311 A.D. and gave special privileges to the city. The castle was a major base and bastion of the Catalans. The external walls of the Castle are surrounded by a steep rocky hill, which ends up to a gorge. Livadia was the third Greek city to raise the 1821 Revolution flag after the cities of Kalamata and Salona, in the highest tower of the Castle. On June 26, 1821 the people of Livadia abandon the city which was under the Turkish rulership and escaped to the mountain; 60 people died that day.
 The Castle after many restoration works, the reconstruction of wooden floors and the placement of new wooden ladders, is accessible to the public. Nowadays it is used as an exhibition space of three levels. Its location is unique, offering a panoramic view of Livadia and the wider region. Walking around the pine trees and the crumbling Catalan walls, you can reach the church of Agia Sofia, which offers a fantastic view of the gorge.
