Bronck House, built in 1663, is the oldest house in upstate New York located in Coxsackie. Pieter Bronck established his family home after settling on 1,900 acres and has served various functions over centuries. The Bronck family and their descendants contributed significantly to local history, including supporting the Patriot cause during American Revolution. The property has remained open to the public since 1939 and showcases early Dutch architecture.
