Yeah, Boston has a lot of squares, most of them not in the shape of squares. Some are even corners (my favorite) or circles. Andy Woodruff has spent some time mapping the squares. Good lookin! He also has a really cool blog where he maps Boston in every which way–by radio station, tree, MBTA traffic– called Bostonography.
And if you’re so inclined, you can buy a poster of Unmapped Boston.
