South Holland, IL
South Holland is a village in Cook County, Illinois, United States and serves as the seat of Thornton Township. The population was 22,147 at the 2000 census.
The area currently occupied by South Holland, Illinois was first settled in 1846 by immigrants from South Holland, Netherlands. When the community formally incorporated as a village in 1894, its population was about 1,000. Originally a general farming community, it later specialized in vegetable growing, especially onion sets. By the 1940s South Holland was known as the Onion Set Capital of the World. The town was built on low ground near the Calumet River and was originally called de Laage Prairie (Low Prairie) to differentiate it from another Dutch settlement further north on higher ground and called de Hooge Prairie (now the Roseland neighborhood of Chicago).
In October 2007, Forbes.com declared South Holland to be the "Most Livable Metro-Area suburb" of the Chicago metropolitan area.
