The Molar Watchtower, of Muslim origin, was part of the network of fortifications erected by the Muslims, around the tenth century, in a series of hills that dominated much of the region and from where borders were controlled and the main communication channels.
The one located in our town, partially rebuilt to avoid its deterioration, is located a bit more than 2 km from the Plaza Mayor, being accessible by car (continuing the road to the cemetery) or walking (it takes about half an hour). It is located on a promontory, called Cerro de la Atalaya, at an altitude of 879 m, this being one of the highest points in the entire municipality.
This type of constructions, of Muslim origin, were fortifications that served to monitor borders and communications. In case of threat, fires were lit that were seen from one watchtower to the next in order to warn of the danger.
Many of these watchtowers were located on the left bank of the Jarama River (Xarama, a Berber word meaning no-man’s river or border river). They were built during the 9th and 10th centuries, during the emirate of Muhamed I of Córdoba and during the time of Abderramán III, who fortified the main sites of the Middle Mark against the Christians. These fortifications were controlled from the village of Talamanca del Jarama. Thanks to this defensive system, the ports of Guadarrama and Somosierra were also controlled.
In other nearby municipalities they also keep ancient watchtowers of Muslim origin, as well as other buildings and fortifications, such as El Vellón, Venturada, Torrelaguna, El Berrueco, Torremocha del Jarama and Talamanca del Jarama. From this last location, the control of this important defensive system was carried out.
