Roslyn Grist Mill

Roslyn Grist Mill is a Dutch colonial structure at the head of Hempstead Harbor with a rectangular form and traditional wooden frame construction clad in weatherboard. The roughly two-story building measures about 50 feet long and 25 feet wide, reflecting typical mills of its era.

The building was constructed between 1715 and 1741, operating as a grain mill for more than 150 years to serve the local community. After milling operations ended, it was converted into a tea house from 1920 to 1974.

The structure stands as one of few surviving Dutch colonial wooden commercial buildings in America, showing how early settlers organized trade and craftsmanship. You can still see in its construction how Dutch builders applied their methods when establishing new settlements.

The building sits on Old Northern Boulevard at the head of Hempstead Harbor and is easily visible from the water. Visitors should know that the site is currently undergoing restoration work to prepare it as a public museum.

During 2020 restoration work, workers discovered a time capsule containing a milk bottle, coins, and letters dated to 1917. These objects provide a direct window into daily life and local history from the early 1900s.
