The Tower of Homage at Alcaudete Castle

The Castillo de Alcaudete, a medieval hill fortress situated in Spain, stands on the site of a Roman fortification, which was later superimposed with an Arab castle. This Arab castle, built over the Roman ruins, was later taken by the Christians in 1085 during Alfonso VI's reign. The castle features a distinctive polygon shape, adjusted to the terrain escarpments. A noteworthy feature is the Tower of Homage, which has a door on the north side, guarded by two additional towers. The castle was restored to preserve its structural integrity and historical value and today serves as a cultural and tourism site. It does not appear to have any direct connection with the Order of Calatrava.
