The Torre de Belén (Bethlehem Tower) has a square floor plan measuring 7.4 metres on each side and is built with limestone ashlars made up of a rope and two tizones. Access to the tower was by means of two doors that formed a right angle. The outer doorway (to the north) is in the form of a pointed horseshoe arch. The inner door (to the east) is the only one that currently leads to the ground floor, which was converted into a hermitage (hence the name Torre de las Imágenes or Torre de San Benito (Tower of the Images or Tower of Saint Benedict).
The tower has two floors covered by a brick vault in the shape of a hemispherical cap. On the first floor are the entrances to the wall’s walkways (to the north and south, by means of semicircular arches), and to the three openings covered by semicircular arches in the east wall, where the chapel bells were once located. There are two theories about the construction of this tower: one of them defends its Almohad origin (12th century), while others place it somewhat later, in the Christian period.
