Urban structure formed by two distinct areas: Vila Velha, located next to the Castle and with urban morphology of medieval nature and Vila Moderna, further down, arranged in wide streets, avenues and squares, corresponding to different phases of growth. In the highest part of the city, on the ruins of the presumably existing Arab fortress, is the oldest nucleus within the walls. The built structure of the Historic Center accompanies the modeling of the terrain on which it is implanted, accentuated by the walls and the Keep, which, placed at the highest point, constitutes the focal point of the entire cluster. In the area of the Castle, the imposing Torre de Menagem marks the Plaza de Armas to the north, where the Santa Maria Church and the D. Dinis Audience Hall are located to the east, on the S. side, a small viewpoint allows a privileged view to the Serra d'Ossa.
