Union Square is home to Prospect Hill, the site where it is rumored that George Washington first flew the American flag. Whether or not this is true, Prospect Hill is a great place to bring a sacked lunch and view the city of Boston. Like most areas of Somerville, Union Square has had a facelift with new bars and restaurants popping up on every corner. Try PA's Lounge for a few drinks and Neighborhood Restaurant or Machu Picchu to cure your hunger pains. Union Square is accessible by MBTA bus routes 85, 86, 87, 91, and CT2. Also, there is a proposed stop through this neighborhood with the future construction of the Green Line to Medford.
