Great news for water sports fans: a former gasometer at Duisburg-Nord Industrial Landscape Park has been converted into a diving centre with a difference. The diving pool, one of the largest indoor facilities in Europe with a diameter of 45m, is open all year round. At a depth of 13m there are a number of attractions including an artificial reef, a luxury yacht and an underwater bicycle. It's a memorable experience for beginners and advanced divers alike.
