The monastery of Sant Pere de Galligants, of which only the church and the cloister remain visible, is one of the most notable examples of Catalan Romanesque. The date of its foundation is not known, but it already existed in the first half of the s. X. Almost nothing remains of the pre-Romanesque monastery, although remains of an earlier building have been preserved. The construction of the current building began in the first half of the 12th century, around 1131, when Ramon Berenguer Gran bequeathed an important donation to support the works. At the end of this century the cloister had to be finished.
