There are remains of a Moorish fort on the hill commanding the town; and the north gateway - the Puerta del Colegio - is a fine lofty arch, surmounted by an emblematic statue and the city arms. The most prominent buildings are the episcopal palace (1733), with a frontage of a 600 ft.; the town house (1843), containing important archives; and the cathedral, a small Gothic structure built on the site of a former mosque in the 14th century, and enlarged and tastelessly restored in 1829.
The chief river flowing towards the Atlantic is the Bidasoa, which rises near the Puerta de Maya, and after flowing southwards through the valley of Baztan takes a north-easterly course, and for a short distance above its outfall at Fuenterrabia constitutes the frontier between France and Spain (Guipuzcoa); by far the larger portion of Navarre is drained to the Mediterranean through the Ebro, which flows along the western frontier and crosses the extreme south of the province.
