A quarter of the Netherlands lies below sea level. Not only on the coast, but also inland, the countless canals, ditches, ponds, rivers and lakes make water the dominant element. With mills, polders, dikes and pumping stations, the country has learned in an impressive way how to deal with water and use it for its own purposes. This can be experienced at many places, e.g. at the Afsluitdijk, the famous final dike, at the Deltawerken or in the Weerribben-Wieden National Park.
