Post Office Square was the site of the first post office in America (1639). The park in the square was made possible when an old parking garage was torn down and replaced with an underground parking facility in 1991.

In the center of Post Office Square is the Norman B Leventhal Park. The 1.7 acre park’s centerpiece is a walk-through sculptural fountain. More than a hundred different species of plants, flowers, bushes and trees are within the park.
