The patron saint of Palombara Sabina is Saint Blaise, celebrated on 3 February in the Church of San Biagio.
During the patronal feast, families who have requested it are given a small statue of the saint, called the «mazzetta», to host in their home until the following year. The Feast of Saint Anthony the Abbot is also held, featuring a procession and the blessing of tractors, once reserved for animals. The town holds the Abbey of San Giovanni in Argentella and the Castello Savelli Torlonia.
