Roslyn Grist Mill

Roslyn, 1384 Old Northern Boulevard
Not open to the public

The Roslyn Grist Mill dates to between 1715 and 1745 and is one of the few remaining Dutch-framed Colonial commercial structures in the U.S. The property remained a working mill until the early 20th century, when it was converted to a teahouse and museum that remained in business until 1975. The following year, Nassau County acquired the mill, which is closed to the public.
