The patroness of Sant'Alessio Siculo is Our Lady of Mount Carmel, celebrated on 16 July. In the district that bears her name stands the church dedicated to her, also dating from the Norman period; in the same area old residential buildings, some now abandoned, are still visible.
On the promontory of Capo Sant'Alessio, within the municipal territory, stands a castle from the Norman era; on the mountainous slopes of the cape also remain the ruins of lime kilns once used for lime processing.
