PIETRAPERZIA, in Enna province is one of those uniquely old hill towns overlooking the Valley of Himera where it is thought the original inhabitants of Sicily dwelled. The castle, built by the Arabs and modified by the Normans is now a ruin and an attraction not to missed as it offers a spectacular view of the valley and Caltanisetta. The town consists of an upper and lower part and there are many events there all during the summer.
