3. Union Square Park
Union Square Park has had an illustrious past. The completion of the Croton Aqueduct was celebrated there, the funeral processions of Presidents Andrew Jackson and Abraham Lincoln passed through there, and the first labor day parade was held there. Prior to becoming a park at the union of Bloomingdale Road (Broadway) and the Bowery (Fourth Avenue), the land served as a potter’s field until 1807. It is possible that when the Commissioner’s grid was being planned, it created Union Square out of the remains of that potter’s field.
