Vilela Bridge is made of granite masonry, composed of four perfect arches. The arches are supported by three blind piers, reinforced with triangular cutwaters upstream and quadrangular ones downstream.
The spans of the two lateral arches are currently obstructed. The tray is horizontal over the central arches and rampant in the tops, paved with granite slabs.
It is hard to attribute a date to this bridge, for its technical and building traits are from the Medieval Period; it may correspond to a time when the need to circulate grew in the Sousa Valley, associated with the need to cross over the Sousa river’s natural obstacle.
