The Torres de Serranos, dating from the late 14C, was one of the city's defensive gateways along its protective walls and is a fine example of medieval military architecture. It also had a function as a triumphal arch, which explains the fine Gothic carving above the door that once gave onto the exterior of the town. The rooms on the city side all give onto loggia, designed in such a way to avoid the enemy being able to seize them. The Torres de Quart opposite date from the 15C.
