Welcome to the Middlesex County Historical Society

We are open! Tuesday and Wednesday from 10 a.m. to 3:00 p.m., or by appointment. Please email [email protected] to schedule a time for research.

Our current exhibit is A Vanished Port, which will end soon. We are preparing our new exhibit, St. Sebastian Feast in Middletown to coincide with September's Feast.

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.


Jesse Nasta, Ph.D., is the Executive Director of the Middlesex County Historical Society. Jesse is a Middletown native, a former MCHS board member, and teaches history in Wesleyan University’s African American Studies Department.

2021 Classic Car Show's Featured Car 1966 Chevrolet Impala SuperSport

All eyes at the Middlesex County Historical Society’s 35th Annual Antique Car Show and Fall Harvest Market will gravitate to this year’s featured car, a 1966 Chevrolet Impala SuperSport. It has Strato bucket seats and power steering and has won over 30 trophies at various shows throughout the years.

It will motor to the show located at Palmer Field adjacent to Washington Street, Route 66 in Middletown on Sunday, October 3. Car registration begins at 9:30 am and judging starts at 11:30 am with trophies awarded to the top vehicles at 2:00 pm. General admission is $3.00 and children 12 and under are free. Car registration is $10.00. Although cars registered for judging must be dated 1996 or older, there is no cut-off date for cars being placed in the car corral. In case of rain, the show will be held Sunday, October 10.

This Impala sports its original 327/275 horsepower engine, its Chateau Slate color and rare factory built air conditioning, and has only 56,000 miles on the odometer. It was restored over a period of four years by its second owner in West Chester, PA. The third and current owner, Jim Caruso, says “Of all the classic cars that I have owned, this one is by far my daughter’s favorite, therefore it is not for sale!”
