Surrounded by forests and fields, the church of Santa Susanna de Peralta is a small Romanesque temple with more than one thousand years of history and extraordinary beauty. The main features that give this building its personality are the bell tower with two half-pointed arches and the nave with a semicircular apse.
It is located about 200 metres north of the castle, in a hollow beside the right bank of the Peralta stream. It has a single nave with a semicircular apse that was the subject of remarkable reforms in the 17th and 18th centuries. It is in a good state of conservation thanks to the significant restoration that took place in 1976 and 1977. The apse is decorated with Lombard slats or lashes, and has a double-bottom window and rounded arches.
At the north side of the temple, at the far end of the nave, there is a square-bell tower that was unfinished or partly demolished. At the moment only the bottom part remains up to the height of the cover of the nave. On the east wall of this tower a bell tower was built with two rounded arches on rectangular pillars, also Romanesque. The interior of the bell tower is connected to the nave by means of a mid-point arch, from the baroque period.
