The Barcelona Royal Shipyard (Catalan: Drassanes Reials de Barcelona; Spanish: Atarazanas Reales de Barcelona) is a shipyard and former military building of Gothic architecture placed at the Port Vell area of the Port of Barcelona. Nowadays it houses the Barcelona Maritime Museum. Construction started during the 13th century under the rule of Peter III of Aragon. During excavations in 2012 it was discovered that in the late 16th century a new building was constructed on top of the old medieval dockyard, giving the building its actual structure. This excavations also uncovered a Roman graveyard. The shipyard's restoration was finished in early 2013. The Museum still holds temporary expositions but is being modernized and will be reopened in 2014 .
