Originally this church was built in the Thirteenth Century by Domenican friars, and had a much wider structure, with a large adjacent cloister. Part of the church was demolished during Mussolini's Fascist rein in order to build a female military academy (one of the first ones in Italy). Today, the Church of San Domenico has maintained its wonderful Gothic façade and inside the splendid funeral monument to Cardinal De Braye, made by Arnolfo di Cambio.
