The Jarama Valley
The municipality of Patones is composed of the towns of Patones de Arriba and Patones de Abajo. If anything characterises this municipality is the variety of landforms. Of El Atazar reservoir and Lozoya and Jarama rivers run through the term and its waterways are numerous important examples of the hydraulic heritage: the old dam of the pontoon of the olive, the dams of Navarejo and la Parra, the dam of Valdentales, in the place known as the "joint of the two rivers" because it joins the Jarama and the Lozoya. Also, the municipality travels through numerous canals with their corresponding siphons and beacons of great importance in civil engineering of the late nineteenth century. The channel of the Lozoya or la Parra, the channel of the high Jarama and the Atazar, they spread the limestone wall that dominates the Valley of the Jarama from the pontoon of the olive to Torrelaguna.
In this town has been found a cave belonging to the Stone Age, which continued to be used during the Neolithic and Bronze Age. On the Cerro de la Oliva we find remains from the Iron Age to the Christian era. For a long time it was a forgotten neighborhood of Uceda, which led them to appoint their own king within the town to administer theself until King Charles III gave them the independence of Uceda. In the 20th century, many inhabitants of Patones (today Patones de Arriba) they went to live in a new urban center nearby, distinguishing between Up ducks and Down Ducklings. The first has been declared of Cultural Interest.
The remains of the ancient Canal de Cabarrus stand out because of its importance, heirs of the important tradition of gardeners that continues today. There are avenues of service of hydraulic infrastructures, such as the Upper Jarama Canal and the Canal de la Parra. The cave of the Reguerillo, declared a historic-artistic monument in 1944, It is located in the mountains and has great interest in its various formations of stalactites and stalagmites.
