Gay City State Park is a public recreation area on the Blackledge River in the towns of Hebron and Bolton, Connecticut.

In addition to its deep forest, millpond, and marshland, the park bears trace remnants (foundations, stone walls, and ditches) of the mill town that occupied the site for most of the 19th century.

Village history has also been burdened with tales of community tensions caused by the free use of alcohol during twice weekly religious services and of grisly murders gone unpunished.

[4] Following construction of a sawmill and wool mill, the village became known as Factory Hollow and grew to about 25 families, many of whom bore the surname Gay.

[5] The property was sold to the state by one of the town's last descendants in 1943, at which time the name Gay City was bestowed on the site.
