Caccamo, in our opinion is one of the most beautiful towns to visit on Sicily's western coast, yet hundreds of thousands of visitors pass it by when traveling along the coatal highway.

The official founding of Caccamo was not until 1093, when the Normans started to build the castle on a rocky spur overlooking a cliff, Castello di Caccamo. The castle itself is actually now being slowly converted into a museum. On the ground level of the castle is a restaurant "A Castellana". Submerged within the Rosamarina 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 Chiesa dell'Anime del Purgatorio (Church of the Souls of Purgatory) 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.
