History
In 1860 the Henry I. Paddock House was completed. It is the oldest surviving structure in the village. In 1871 a post office was built on what would become IL 137 named Spring Bluff. Not only did this spur an increase in population in the area, but it would inspire the name of the Spring Bluff Forest Preserve. Of which the state began purchasing land for in 1963.
J. H. Van Vlissingen originally intended on developing the area in 1883, however nothing came of it. In 1899 the Winthrop Harbor and Dock Company purchased over 2,000 acres just south of the state line of Wisconsin. Winthrop Harbor was incorporated as a village in 1901.
Despite the intention of the settlement to be an industrial district, the village remained mainly residential until 1989 when the North Point Marina was constructed. Until the modern day the marina is considered the pride and soul of village.
