Viaducto de los Quince Ojos, Madrid

The Viaducto de los Quince Ojos is a stone viaduct in Ciudad Universitaria featuring fifteen arches that cross the Cantarranas stream. The structure connects different parts of the city and parts of it remain in use for traffic today.

The viaduct was built by engineer Eduardo Torroja between 1929 and 1933 to support the road to La Coruña entering Madrid. It was among the first modern infrastructure projects to serve the expanding city of that era.

The structure bears bullet marks from the Spanish Civil War, when it served as a defensive position between opposing forces. These marks remain visible today as traces of that conflict.

Only two of the fifteen arches remain open for vehicle and pedestrian traffic, while the others serve various functions including storage. The viaduct can be viewed from outside and offers interesting perspectives from different angles.

Ownership of the viaduct is fragmented: three arches belong to Complutense University, nine to the Ministry of Development, and one to Madrid City Council. This unusual division reflects the complex history of urban development in the area.
