The province includes the southwestern part of the Rhine-Meuse-Scheldt delta. It consists of a number of peninsulas that once were separate islands. The name "Zeeland" is derived from this. The peninsulas and the former islands are: Tholen, Sint Philipsland, Schouwen-Duivenland, Noord-Beveland, Zuid-Beveland and Walcheren. In addition, you have completely closed off from the province of Zeeuws-Vlaanderen that is not an island.
