The castle, marking the limit of the walls of the Villa, is one of the smaller sides of the Plaza Mayor.
Attached to the bottom of its turrets a building of the s. XVIII, with a running balcony, supports the "Clock of the Plaza". Cultural exhibitions are currently held in this building; and from its balcony the "chupinazo" announces the start of the Fiestas de los Toros. It is possible to follow the layout of the wall in some areas, such as the section called Trascastillo and the Postiguillo area. Some of its Seven Doors are conserved. At the entrance to the street that leads to the shrine of Ntra. Sra. De la Peña is the so-called Puerta del Azogue, which is also known as the Ecce Homo. On the outskirts, on the way to the Natural Park of the Hoces del Río Duratón, we can see the remains of the Puerta de la Fuerza, from which a Roman road leads to the Puente de Picazos. In the neighborhood of San Esteban is the Puerta del Río, next to the niche of the Virgen de las Pucherillas.
