The fortress of Livadiá, which stands on top of Mount Ágios Ilías (402m), controls the approaches to Thessaly. The position was first fortified in the 13C by the Franks, who held Thebes, but the present fortress dates from the 14C when the Catalans ruled the land. The former outer bailey of the castle precedes the main gate, which leads to the keep. Near it stands the chapel of Elijah built on the site of a temple to Zeus.
