Valderrobres is the most outstanding town of Matarraña. Entry is gained over the medieval bridge of San Roque, held up by pointed arches. Its urban layout is composed of narrow, winding little streets which creep up the hill in search of the two most emblematic buildings: the castle from the 14th century (without a doubt, the most spectacular and artistic of all the province's castles) and the church of Santa María la Mayor, from the 16th century and declared to be Historic-Artistic Heritage, whose tower is connected to the castle by a passage. The church is a fine example of Teruel's Gothic style, whose façade is decorated with a magnificent rose window.
There are also a great many civil buildings worth mentioning: the gate of San Roque or the Gate of the Lions (14th century); the door of Bergos (13th- 14th centuries), above which there is a house; or the City Hall (16th century), a Renaissance building with a huge Aragonese gallery of semicircular arches, declared to be a National Monument.
