Founded in 1901, the Middlesex County Historical Society is a not-for-profit organization dedicated to preserving the history of Middletown and Middlesex County, and providing programs for adults and children to increase their understanding of the area’s past.  Museum exhibits, walking tours, re-enactments, and a lecture series are among its many annual events.


The Historical Society is headquartered at General Mansfield House, one of the few residential structures still standing on Middletown’s Main Street. Once the home of General Joseph K.F. Mansfield, a Civil War hero who died at the battle of Antietam in 1862, the Federal brick mansion has been the home of the Historical Society since 1959.

At the museum at General Mansfield House, visitors can explore the community’s past through major exhibits, which showcase artifacts from the Historical Society’s permanent collection. Recent exhibits have examined artifacts from World War I, Middletown’s 19th century women’s clothing, varied immigrant groups; the rise and fall of manufacturing in Middlesex County; and, death and dying from Colonial times to the present. A Vanished Port, our current exhibition, explores Middletown’s history as a colonial port.

  1. I assume it got its name because the Connecticut River ferry that ran back and forth between Middletown and Portland left from this street’s (one-time) intersection with the River. Perhaps someone can verify that for us?
