The Dutch Navy Museum in Den Helder.
The Marinemuseum is the Dutch Navy Museum. Being an important part of Dutch history, it has extensive displays. The accessible submarine Tonijn (Tuna) is a memorable experience on its own. The ships-bridge and radar dome of De Ruyter is impressive. The exhibition following the history of the Dutch Navy through the Golden Age and WWII to modern times is informative. Another building shows the history of the dockyard and naval technology.
