The El Gasco Dam, also known as the Peña Strait or Carlos III Dam, is one of the most important civil engineering projects in 18th-century Spain. It is located on the gorge of the Guadarrama river, in an area currently protected by the Regional Park of the middle course of the Guadarrama river and its surroundings.

Built in granite masonry in the Guadarrama river canyon, it was the tallest dam projected up to that time, with 93 meters in height, although it only reached 53 meters built. The first operators were soldiers and later common prisoners were brought in to lower costs. The current remains are 251 meters long, 72 wide at the base and four at the top. The pressure of the water and the leaks caused the collapse of the south wall in 1789, mainly due to technical deficiencies in the construction.
