Holland refers to the western region of the Netherlands. The etymology of Holland comes from the Middle Dutch term holtland (wooded land). Many areas of Holland are below sea level, requiring constant drainage. This lead to the ubiquitous Dutch windmills, used for pumping water.

Holland contains four major cities, Amsterdam and Utrecht in the Noordvleugel (North Wing), and The Hague and Rotterdam in the Zuidvleugel (South Wing). These four nodes link with other cities to form the Randstad (rim city). The Randstad has seen many proposals over the years to link the region through high speed rail and international motorways.
