Built at the end of the fourteenth century for the manufacture, storage and repair of vessels, they played a decisive role in the commercial and maritime prosperity of medieval Valencia.
Declared a National Historic-Artistic Monument in 1949, they constitute an Asset of Cultural Interest. Currently, only the core of the primitive complex remains, a vast rectangular building with an approximate surface area of 3,500 m².
Gothic building with five parallel naves supported by diaphragm arches built in tile. On each of them rests a simple roof of tiles with double water. They were built at the end of the fourteenth century as a shipyard, arsenal and warehouse of navigation effects of the city.
At the time of its construction they were located at the northern end of Vilanova del Grau, a little separated from it and surrounded by a wall and a small moat. The complex was completed with several outdoor courtyards in which there were rafts for “mixing” wood and jugs for storage. Originally, the ends of the ships did not have to be blinded to allow ships and galleys to enter and exit. The shipyards stood a few meters from the coast on the sand of the beach, a location that today is difficult to imagine due to the existence of the port and, above all, because of the buildings that stand on the front line covering the access to the sea.
