Welcome to the Lake Ronkonkoma Historical Society

The Lake Ronkonkoma Historical Society's mission is to celebrate and preserve the rich history of the Lake Ronkonkoma area. We operate two museums, The Ronkonkoma Free Library building was originally opened in 1916 and is now the Lake Ronkonkoma Historical Society Museum. The Fitz-Greene Hallock Homestead Museum is a 14-room home built in 1888 and is complete with all the original Hallock family furnishings. Since the Historical Society’s formation in 1976, we have collected thousands of historical Ronkonkoma artifacts and photographs. The Historical Society offers various tours and programs throughout the year at both locations
