The patron saint of San Felice Circeo is Saint Felix the Martyr, celebrated on 29 July.
On Pentecost Monday, the feast of Santa Maria della Sorresca is celebrated, the Madonna that, according to legend, was found by fishermen in the waters of Lake Paola. Particularly venerated by the townspeople, the feast is marked by a large, traditional pilgrimage that sets off at six in the morning from the historic centre and reaches the shores of the lake. The town also holds the Torre dei Templari and the Torre Paola.
