The official founding of Caccamo was not until 1093, when the Normans began building the castle on a rocky spur overlooking a cliff. The castle itself is actually now being slowly converted into a conference center. Submerged within the lake is a stone bridge built in 1307 on the road that once linked the town with Palermo. The city contains an attractive 11th-century cathedral, which was remodeled in 1477 and 1614. On the side of the cathedral are two churches. The Chiasa dell'Anime del Purgatorio features some stucco work in the eastern end and an 18th-century organ. In the downstairs are catacombs where the skeletons of a number of townspeople lie in niches along the wall, a burial practice that lasted from the 17th century up to 1863.

Since the 1950s the town itself has lost almost half of its inhabitants to emigration. Caccamo holds some great views of the surrounding countryside, including the Rosmarina artificial lake, which was created by a controversial dam built in 1993.
