Torre de Calígula
This important and solid semicircular stone wall is a reworking of a cylindrical tower of great proportions. During the Andalusian era, Cazalilla belonged to the Cora de Jaén, with the name Qastalla. It was at this time that the castle acquired real importance when it received a military use, as it would have been of great strategic importance in monitoring the south of the Guadalquivir River and Espelúy. The Calígula tower was classified as an Asset of Cultural Interest in 1985. Located in Plaza Constitución.
