Wonders of Somerville (Union Square)

   Somerville is, like Boston, another town that borders Cambridge. Sumvul has several different neighborhoods, which all have their own character. Houses, three-deckers and apartment buildings are in a variety of styles. Much of the housing stock seems to have been built between the Civil War and 1900– and almost entirely of wood. Buildings featured in this post are all in the Union Square neighborhood.

I'm trying to learn more about this brick building, corner of Bow and Summer Streets. 1870s?
Queen Anne style, and over several tops!
