Explore the History & Culture of New Jersey's Greater Raritan-Millstone River Valley!

We are a group of historic and culturally important sites in Middlesex, Mercer, and Somerset counties, along with parts of Hunterdon, Mercer,  Monmouth and Union counties - all nestled along the Raritan and Millstone Rivers running through central New Jersey.

Our mission is to promote the preservation and understanding of the rich cultural heritage embodied by these over-140 significant historical, educational, and cultural sites, including non-profit and educational entities, museums, commercial, private homes, and even restaurants.

We encourage members to tour and enjoy these sites!
