Built in 1889-1890 in Rockville (part of Vernon) to serve as the Town Hall, the second floor features a Grand Army of the Republic Hall. It is the longest continuously operated GAR hall and the only one still intact with its original contents in Connecticut. Today it is open to the public as the New England Civil War Museum. The museum displays original stained glass windows and Civil War artifacts, including the Thomas F. Burpee Collection and the Hirst Brothers Collection. Originally planned to be constructed of wood, it was eventually decided to build the Memorial Building in stone, as the nearby Congregational church, which had been made of wood, burned down twice! After the church burned down in 1888, the new Union Congregational Church of 1890 was also built in stone. The Memorial Building was built by GAR veterans, one worker falling to his death during the construction. In Central Park in front of the building is the Cogswell Fountain, donated to the town by the temperance activist Henry D. Cogswell in 1883.
