Hoofddorp (Dutch pronunciation: [ˈɦoːvdɔr(ə)p]; lit. ’Main Village’) is the main town of the Haarlemmermeer municipality in the province of North Holland in the Netherlands. In 2021, the population was 77,885. The town was founded in 1853, immediately after the Haarlemmermeer had been drained.

In the late nineteenth century Hoofddorp was included in the Defense Line of Amsterdam.[3] A fort was built next to the main canal, two batteries were located in what are now the outskirts of Hoofddorp, and several casemates were built to the east of Hoofddorp. A large dike known as the Geniedijk (Engineers’ dike) connected the fort at Hoofddorp to the batteries and the casemates, and ultimately to the fort at Vijfhuizen in the west and the fort at Aalsmeer in the east.

In 1856, the first windmill in the Haarlemmermeer was built in the centre of Hoofddorp by Dirk David van Dijk. It was called “De Eersteling” (The First). Due to increased building around the mill it eventually fell into disuse. In 1977 the mill was moved to another location near fort Hoofddorp. It has operated regularly from that time and is now open to the public.
