Housed in a humungous former arsenal built in 1656, the National Maritime Museum reopened in 2011 after extensive reworking and is dedicated to showcasing the importance of Amsterdam’s maritime history. During the 17th-century Golden Age, The Netherlands was one of the richest powers in the world, thanks to its trading wealth and an empire that stretched across the globe. It was a time of great progress in Amsterdam, when the Canal Ring was built and the middle classes grew rich. All this is reflected in interactive and audio-visual displays of model ships, maritime oil paintings, charts, silverware and weaponry; the growth of the fabulously successful Dutch East India Company (Vereenigde Oostindische Compagnie or VOC) is charted and visitors are whisked on a simulated journey through Amsterdam as a piece of cargo. Two now controversial issues that are dealt with sensitively through thoughtful exhibits are the European slave trade and the whaling industry.
