The Hudson River National Historic Landmark District (HRNHLD) was designated by the U.S. Secretary of the Interior in 1990. Federal landmark status acknowledges that the historic resources in the heart of the Hudson Valley are of the highest national significance, on par with other National Historic Landmark Districts such as Nantucket Island, the Garden District in New Orleans, and San Francisco’s Presidio. The HRNHLD evolved from two previously designated areas: the 16-mile Estates District and the Clermont Estates District.
This extraordinary 32-square-mile district stretches from Germantown in Columbia County to Hyde Park in Dutchess County. It is comprised of four towns, four hamlets, two villages, over forty riverfront estates, and the designed landscapes, farmland, and distinctive natural features in between. To a remarkable degree, the character of the Hudson River National Historic Landmark District remains intact. HRH sponsored the research and led the process culminating in this prestigious National Historic Landmark designation, and now acts as its federally-recognized steward.
