The patron saint of Marostica is Saint Simeon, celebrated on the last Sunday of October.
Every first Sunday of the month, an antiques market is held in the chess square and along Via Mazzini. Late May brings the Cherry Festival, while since 2007, the second Sunday of June, the Palio dea Caretera is run, reenacting the old Marostica cart race held in 1956-1957-1958. The town holds the Church of Santa Maria Assunta and the Museum of the Costumes of the Chess Game.
