The Masos viaduct was built in 1889 over the ravine of the same name, in the railway line from Tarragona to Zaragoza. Its length is 218 m and its height of 36 m. It was built with stone blocks in the corners and reddish brick in the walls and vaults. In October 1938, in the Spanish Civil War, the central section was blown up. Later, it was rebuilt with concrete.
