El Vellón

Highlight • Settlement

There are two clearly differentiated urban centers, a beautiful watchtower of Arab origin, lots of traditional architecture and Los Quebraones, a very interesting natural area.

Church of Santa María Magdalena

Highlight • Religious Site

It is a beautiful church, in the Gothic style, built in the 14th century and one of the best exponents of Elizabethan or late Gothic in the peninsula, and especially in the Community of Madrid. The altar is something incredible! Only open on Saturdays and Sundays.

View of El Atazar Reservoir

Highlight • Viewpoint

It is the largest reservoir in Madrid. There is a viewpoint that is at a height above the wall of the dam from where you can see the development of the reservoir and its tail.

El Berrueco Watchtower

Highlight • Monument

It is worth it for the incredible views that can be seen from the top. A complete panoramic view of the Atazar but it is difficult to get there with a road bike. Likewise, from the road you can see the views and the tower itself is El Barrueco.
