The city of Rotterdam is located on the banks of the North Sea by the Nieuwe Waterweg and is different to other Dutch destinations. Recognised as one of the world's leading ports, this ever-evolving city has a wealth of attractions. With its modern skyline, industrial port and hardworking heritage, the Netherlands’ second city has always been outshone by its pretty sibling Amsterdam, the quaint capital. Rotterdam offers something for everyone - those who love the hustle and bustle of city life and those searching for peace tranquillity. One of Rotterdam's 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.
