It is a brick building dating to the 1890s. In 1975 it was listed on the National Register of Historic Places.It was built to serve both as headquarters for the local militia and as a community gathering place. It served a variety of community-related functions, eventually becoming city hall in the mid-20th century. Later in the century, as the city grew again into an affluent resort community, it had to move some of its departments to other office space and renovate the city hall extensively, particularly inside.
