For nearly 170 years Union Square has been a gathering place—for commerce, for entertainment, for labor and political events, and for recreation. The park owes its name to its location at the intersection—or union—of two major roads in New York City, Bloomingdale Road (now Broadway) and Bowery Road (now Fourth Avenue). When the Commissioner’s Plan, the famous gridiron of Manhattan streets and avenues, was projected in 1807, the former potter’s field at this intersection was designated as Union Place. The site was authorized by the State Legislature as a public place in 1831 and acquired by the City of New York in 1833.
On July 19, 1839 Union Square opened to the public. Its paths, situated among lushly planted grounds, were inspired by the fashionable residential squares of London. The design emphasized the park’s oval shape (enclosed by an iron picket fence) and focused on a large central fountain, which was installed for the opening of the Croton Aqueduct in 1842. As New York City’s downtown expanded northward, Union Square became an important commercial and residential center. Around its borders sprang up houses, hotels, stores, banks, offices, manufacturing establishments, Tammany Hall, and a variety of cultural facilities, including music auditoria, theatres, and lecture halls. The grounds of Union Square have frequently served as a choice location for public meetings, including parades, labor protests, political rallies, and official celebrations such as the Great Metropolitan Fair of the U.S. Sanitary Commission in 1864.
In 1871 Parks Engineer in Chief M.A. Kellogg and Acting Landscape Gardener E.A. Pollard collaborated on a new plan for Union Square. A year later the park was redesigned by landscape architects Frederick Law Olmsted and Calvert Vaux. They removed the enclosing fence and hedge, planted a variety of hardy trees, widened the sidewalks, and created a muster ground and reviewing stand "to meet the public requirement of mass-meetings."
