The patron of Pesaro is Saint Terentius, celebrated on 24 September; a painting of him by Terenzio Terenzi once hung in the church of Sant'Ubaldo, in Largo Mamiani.
Pesaro is the birthplace of composer Gioachino Rossini: his house-museum, the conservatory, the theatre and the national museum dedicated to him all bear his name, and since 1980 the city has hosted the Rossini Opera Festival every summer.
