Union Square's location at the juncture of working-class East Somerville and the city's tonier western sections have made it the focal point of changing demographics. More upscale cafes, bars, and restaurants have opened since the 1990s, bringing gentrification deeper into Somerville. Union Square Main Streets, a local development group, began running a Saturday morning farmers' market in 2005 as one of its first visible efforts in the square. A landscaped community garden with regularly scheduled concerts and artistic events sits just outside Union Square at the site of an old school.
