Warrenville was founded in 1833 when Julius Warren and his family moved west from New York seeking a fresh start from a failing gristmill and distillery. Daniel Warren, Julius’ father, claimed land at what is now McDowell Woods, and Julius claimed land at what is now the Warrenville Grove Forest Preserve. The first major establishment, an inn and tavern, was built in 1838 by Julius Warren himself, as the family was skilled in timber and grain. The inn still stands today, and was renovated in 2002.
Warrenville has since become a hub of business activity, with dozens of firms calling it home by 2020.
