The town of Cefalù, as well as the Cathedral, are nestled under an imposing brown calcareous-rock mass; the “dolomia calcarea”, known as the “Rocca”. In ancient times, this was the place where the “lumachella” stone was quarried and used to make the paving stones for the Cathedral. The Rocca is protected as a site of community interest in Sicily. It has a height of 268 meters and is part of the Madonie chain.
