The Church of the Unity is also featured in this post, although the photo in that one is close to 100 years older than this “before” one is. As mentioned there, this church was significant as the first commission of architect Henry Hobson Richardson, and was built between 1866 and 1869. However, it was demolished only two years after this photo was taken, and was replaced with a parking lot for the Springfield Public Library.
