The Museum of Maritime Affairs of Barcelona (Museu Marítim) has a 75-year history dedicated to the protection and dissemination of marine culture, and the collection of maritime artifacts occupies a significant position in the Mediterranean region. The Royal Barcelona Shipyard is part of the Maritime Museum and is one of the world's best preserved Gothic architecture and one of the most important symbols of the shipbuilding industry in the Mediterranean. The Maritime Museum is located near the Columbus Monument. We went to the bathroom to enter the side section of the museum and did not enter the museum to visit the collection.
