Hoorn is a city and municipality in the northwest of the Netherlands, in the province of North Holland. It is the largest town and the traditional capital of the region of West Friesland. Hoorn is located on the Markermeer, 20 kilometers east of Alkmaar and 35 kilometers north of Amsterdam. The municipality has just over 73,000 inhabitants and a land area of 20.38 km², making it the third most densely populated municipality in North Holland after Haarlem and Amsterdam. Apart from the city of Hoorn, the municipality includes the villages of Blokker and Zwaag, as well as parts of the hamlets De Bangert, De Hulk and Munnickaij.
Hoorn is well known in the Netherlands for its rich history. The town acquired city rights in 1357 and flourished during the Dutch Golden Age. In this period, Hoorn developed into a prosperous port city, being home to one of the six chambers of the Dutch East India Company. Towards the end of the eighteenth century, however, it started to become increasingly more difficult for Hoorn to keep competing with nearby Amsterdam. Ultimately, it lost its function as port city and became a regional center of trade, mainly serving the smaller villages of West Friesland.
