At America's first post office, you could order a beer. In 1639, the Court of Massachusetts designated a tavern owned by Richard Fairbanks – located between what is now Washington Street and Devonshire Street near the Old State House – as the official mail drop for anything traveling across the Atlantic.
A few blocks away in the Financial District is Boston's famous Post Office Square. The square is home to the John W. McCormack Post Office and Courthouse, as well as Norman P. Leventhal Park. The park runs a range of programming during the summer, including free music (including a Boston Crusaders show this Thursday), free fitness classes, and more.
