Update: More commonly known as the Beaumont Telephone Exchange, the building was renovated into apartments and opened in the spring of 2021.
Built in stages, the Bell Telephone Exchange, or AT&T, depending on how you look at, is an interesting example of early 20th Century utility architecture. Showing the influence of the Beaux-Arts style, this building could have easily just been a giant brick box.
But clearly its builders believed that people deserved better than that, and this building is much more ornate than it needs to be functional. I love the two telephone booths that still stand inside the fence.
