Buitenkaag is a village in the Dutch province of North Holland. It is a part of the municipality of Haarlemmermeer, and lies about 8 km northeast of Leiden. The name Buitenkaag (Outer Kaag) refers to the town Kaag and the surrounding lake area, the Kagerplassen. The village officially received the name in 1859.[3]
One of the most distinctive buildings in Buitenkaag is "Gemaal de Leeghwater", a pumping station named after Jan Leeghwater. Built in the mid-19th century to reclaim the Haarlemmermeer lake, it is still operational today. Originally, it was based on steam engine. In 1930, diesel engines were installed in the pumping station.[4]
