Zoetermeer is a city in the western Netherlands, in the province of South Holland. A small village until the late 1960s, it had 6,392 inhabitants in 1950. By 2013 this had grown to 123,328, making it the third largest population centre in the province of South Holland, after Rotterdam and The Hague. It is part of the Haaglanden conurbation. The name Zoetermeer (Dutch for "freshwater lake") refers to the former lake north of the town (reclaimed in 1614). Because the name literally translates as "sweet lake" local residents have dubbed Zoetermeer "Sweet Lake City".
