The patron saint of Castel Madama is Saint Michael the Archangel, celebrated on 9 May in the Church of San Michele Arcangelo.
The Palio Madama Margarita d'Austria is an event that recalls the 1538 entry of Margaret of Austria, daughter of Emperor Charles V, into the fiefdom that later took her name. The town also holds the Castello Orsini and the Roman Aqueduct.
