Bridge of Cruzul Monument · Becerreá, Ancares, Lugo The Cruzul bridge crosses the Narón river in the parish of Cruzul, in the municipality of Becerreá, on one of the historic routes linking the plateau with Lugo through the western foothills of the Ancares. It was built in the late 18th century, in neoclassical style, as part of the royal road to A Coruña, within Charles III's plan of royal roads, and is considered the first work of modern civil engineering in Galicia. It is a limestone structure 29 metres high and 93 metres long, with an 8-metre roadway supported by three semicircular arches 12 metres in diameter; of the four pyramidal monoliths at its ends, three survive. It forms part of a natural area within the Natura 2000 network and its declaration as a Bien de Interés Cultural (Spain's highest level of heritage protection) has been requested.
