Welcome to the official website for the Raritan-Millstone Heritage Alliance (RMHA). Our mission is to promote preservation and understanding of the rich eventful and cultural heritage of significant historical, educational, and cultural sites located in the Raritan-Millstone region of New Jersey.

Our 140+ sites include commercial, non-profit and educational entities, museums, private homes and restaurants. We encourage members to tour and enjoy these sites.

What is the RMHA?

We are a group of historic sites in Middlesex, Somerset, and Mercer counties, nestled along the Raritan and Millstone Rivers. These sites have a rich, eventful past, and a promising future. It includes adjacent corridors which support these sites. It links Perth Amboy on the Raritan with Princeton on the Millstone.

The Rivers run through a valley rich in the unique heritage and culture of central New Jersey, an area that has continually contributed to the strength of our United States. We want to share this heritage.
