Welcome to the official website for the Raritan-Millstone Heritage Association (RMHA). Our mission statement 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.

To fulfill this mission, the Alliance sponsors programs including the Sunday Series held four times in September, and May of each year. Each quarter, a member site is featured as the location of an informative program. Our 141 sites include commercial, non-profit, and educational entities, museums, private homes, and restaurants. We encourage members to join us for brunch, the program and a tour of the site.

What is the RMHA?

We are a group of Middlesex, Somerset and Mercer County sites, historical and eventful along the Raritan & Millstone Rivers. 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.
