Adirondack Architectural Heritage (AARCH) is the nonprofit historic preservation organization for the Adirondacks. AARCH was formed in 1990 with a mission to promote better public understanding, appreciation, and stewardship of the Adirondacks' unique and diverse architectural heritage.
AARCH's office is located in Keeseville, in the historic Ausable Horse Nail Company's factory office building. It contains the Clayton Family Gallery, which regularly has exhibits on display.
The gallery is open Monday through Friday from 8 a.m. to 4 p.m. Contact AARCH for information on special tours and lectures, as well as for technical assistance.
