Walking tour of Union Square

I’m using this project to get to know my city, Somerville, a little better. Today, I took a walking tour of Union Square. The tour was led by the Somerville Historic Preservation Commission. And it was a quite to tour, with tidbits of architecture and history dating back to the incorporation of Somerville. There was even amazing secret view of the ivy-covered steeple and sanctuary of a former episcopal church, which someone needs to tell Atlas Obscura about. I somehow neglected to take a photo of the church, but I did take one of our tour guide speaking to our group, which was about 40 or 50 people, in front of a hidden mural down a dead end street.
