The Reials Drassanes (Royal Dockyards) of Barcelona are at the end of the Ramblas, to the right of the Plaza del Portal de la Pau.

They date from 1378 and are the biggest and most complete Medieval dockyards in the world. They currently house a big exhibition hall and the Museu Marítim of Barcelona, which includes various collections of boats, paintings, figureheads and an interactive exhibition, "The Great Adventure of the Sea".
