The Bellamy-Ferriday House and Garden embodies the dramatically different passions of two individuals. Bethlehem pastor Joseph Bellamy, a renowned leader of the Great Awakening, the emotional religious revival of the 1740s, built the house around 1754. In 1912, New Yorkers Henry and Eliza Ferriday acquired it as a summer residence. Around 1915, Mrs. Ferriday designed a formal garden with historic roses, peonies, lilacs, and other flowers. The Ferridays' daughter, Caroline, restored the house, furnished it with Litchfield County antiques, and maintained the magnificent garden, refining the property as a combination of natural and manmade beauty.

The house offers tours.
