Geography plays a key role in the Netherlands’ iconic landscapes. More than a quarter of the pancake-flat country is below sea level, and 20% has been reclaimed from the sea, making regimental rows of polders (areas of drained land) omnipresent. Uninterrupted North Sea winds have powered windmills since the 13th century, pumping water over the dykes, milling flour and more. Some two-thirds of the surface is devoted to agriculture, including beautiful rainbow fields of crocuses, daffodils, hyacinths and tulips that burst into flower each year between March and May. The kaleidoscope of color is nothing short of invigorating.
