A barn, constructed in 1782 on the Porter-Phelps-Huntington estate, was moved in 1930 to the rear of the Hadley Town Hall. It is now home to the Hadley Farm Museum, which houses a collection of vehicles and equipment used on New England farms from the eighteenth through the early twentieth centuries. When it was moved, the barn‘s exterior was redecorated with white painted clapboards. A doorway was added, which is a copy of the famous Connecticut River Valley doorway of the Samuel Porter House in Hadley.
