Roslyn Grist Mill
Address1345 Old Northern Boulevard, Roslyn
The Roslyn Grist Mill is a rare surviving Dutch-framed watermill built between 1715 and 1741 purposely built for industrial use (rather than farming). It operated as a working water mill for over 150 years.
• The building is located in the heart of the Village of Roslyn at the head of Hempstead Harbor.
• The Roslyn Grist Mill features a heavy wooden structural frame constructed with post-and-beam joinery, sharing characteristics with New World Dutch buildings found throughout western Long Island and the Hudson River Valley.
• On April 24, 1790, the owner of the grist mill Hendrick Onderdonk was visited by President George Washington in his Roslyn residence adjoining the grist mill. Washington referred to the grist mill in his diary.
• From 1920 to 1974, the grist mill building served as a tea house and was a tourist attraction to the village.
• The building was placed on the National Historic Register of Historic Places in 1986.
• From 2015 to 2020, $3.1 million was from New York State, Nassau County, trusts foundations and members of the government grants, trust awards and members of the Roslyn Landmark Society.
• After 42 years of delays and planning, the restoration began in November 2018 by the Roslyn Landmark Society .
