Clapp House Preservation, Inc. Registered non-profit formed to "conserve, preserve, & protect" the historic Increase Clapp House.

Our Mission:
*To conserve, preserve, and repurpose the historic 1808 Increase Clapp house at 59 Sullivan Ave.
*To enhance an important "gateway" to the town of South Windsor.
*To remind future generations and visitors alike of the town's commitment to honoring its rich heritage. The Clapp House, built in 1808 by local blacksmith Increase Clapp, was home for generations of Clapp's and -since 1938- generations of Schweir's. The house and it's 43 acres of land were sold in 2016 for the development of two large warehouses. That same year, the developer donated the house to the town (along with .91 acres of land) who created a non-profit for it. At the urging of area residents, in 2018 a seven member Board of Directors was named as sole owners and caretakers of the property.

Windsor’s first (and only) serial killer, Amy Archer-Gilligan famously poisoned residents in her nursing home on Prospect Street by using arsenic. You might ask, where did she get all that arsenic? Why at the drugstore in this quaint, hand-colored postcard. Recognize the building? Today it’s the home of Siam Corner Kitchen and the Broad St. Barber Shop. But over a century ago in the 1910s, it instead held the store of druggist W.H.H. Mason. He apparently also sold cold soda, gasoline, and paint, in addition to rat poison.

This postcard was part of a series put out by the Shade To***co Growers Agricultural Association, Inc., Windsor, CT. The back reads: "In harvesting ripe leaves of shade grown to***co, used for cigar wrappers, operators sew pairs of leaves to a string attached to a lath. The laths are hung between rafters in large sheds where the leaf cures."
