The city of Rotterdam is located on the banks of the North Sea by the Nieuwe Waterweg. Recognised as one of the world's leading ports, this ever-evolving city has a wealth of attractions. Rotterdam offers something for everyone - those who love the hustle and bustle of city life and those searching for peace tranquillity. One of Rotterdams main attractions is Diergaarde Blijdorp, a zoo featuring the impressive Oceanium where visitors can walk through an underwater tunnel surrounded by sharks. Rotterdam also attracts a great deal of international interest as a city of architecture. Across a few square miles in the city centre, you can find a complete overview of 20th century developments in modern architecture, from the pre-war Van Nelle Factory, designed around the concepts of light, air and space, to the striking Kubuswoning, or Cube Houses, a signature creation of Dutch architect Piet Blom. For an oasis of peace in the middle of the hectic city, be certain to visit the lovely gardens of Arboretum Trompenburg.
