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 Lake Ronkonkoma Historical Society Museum founded in 1976 which is housed in what was once the Lake Ronkonkoma Free Library and the Fitz-Greene Hallock Homestead which is a 14-room home built in 1888 and is complete with all the original Hallock family furnishings. The Historical Society offers various tours and programs throughout the year.

Now you can visit us on Facebook and enjoy our shared history in an interactive manner!


The Lake Ronkonkoma Historical Society and Museum, founded in 1976, does not endorse and is not supportive of or affiliated with the Lake Ronkonkoma Heritage Association or the Lake Ronkonkoma Heritage Commission.
