The island of Texel was originally made up of two islands, Texel proper to the south and Eierland to the northeast, which were connected by shoals. In the early seventeenth century, the islands were connected by a dyke to keep the North Sea from ravaging the coastal areas of Texel proper. In the mid-nineteenth century a polder completed the northern half of the island. Today, Texel forms the largest natural barrier between the North Sea and the Wadden Sea.
