Rotterdam is Holland’s second-biggest city after Amsterdam, and is known as the gateway to Europe. This buzzing city is famed for the diamond trade, countless shops, and stylish architecture. Whether shopping along the walkway of Lijnbaan, taking a cruise around the harbour, or soaking up the sun on Boompjeskade Beach, there is always something to enjoy. Families love the Blijdorp Zoo and its brilliant Oceanarium, while others take pleasure in strolling around the historical seaport of Delfshaven with its iconic windmill. The Boijmans-Van Beuningen Museum is one of the great attractions of Rotterdam and features an enormous collection of paintings spanning the centuries, from Old Masters to Pop Art. The tower of the 15th-century St. Laurenskerk church offers a stunning view of the city, and for something out of the ordinary visit the Kijk-Kubus, an intriguing upside-down house certain to baffle and amuse. Many popular restaurants, bars and cafes offer live entertainment.
