The Third Meetinghouse, designed by architect and glazier Lavius Fillmore (first cousin once removed to President Millard Fillmore) of Norwich, was dedicated on Thursday, November 27, 1794. (No, that wasn’t Thanksgiving back then. Thanksgiving Day was celebrated one week earlier on the 20th.)
It is the oldest surviving example of the trend-setting, fully-evolved Federal-period meetinghouse style, whose basic design was duplicated extensively across New England and the Midwest for the following 35 years.
The Third Meetinghouse is listed on the National Register of Historic Places as a part of the Little Haddam Historic District.
