Union Grounds was a baseball park located in the Williamsburg section of Brooklyn, New York. The grounds opened in 1862, its inaugural match being played on May 15 and it was the first baseball park enclosed entirely by a fence, thereby allowing proprietor William Cammeyer or his tenant to charge admission. This permitted paying customers to watch the games from benches in a stand while non-paying spectators could watch from embankments outside the grounds. The ball grounds was built on a block bounded by Harrison Avenue, Rutledge Street, Lynch Street. A writer for the Brooklyn Eagle described the field in 1862, The buildings occupied last winter are left standing, near these a long wooden shed has been erected, capable of accommodating several hundred persons, and benches provided for the convenience of the fair sex. Several acres more have added to the enclosure, which is fenced in with a board fence six or seven feet in height. On the southeast corner a large and commodious club house has been erected, the field is now almost a perfect level, covering at least some six acres of ground, all of which is well drained, rolled, and in a few weeks will be in splendid condition. Several flagstaffs have been put up, from which floated the banners of the clubs oer shadowed by the nations ensign. During its early years Union Grounds was the field for several ballclubs. In 1868, the Mutual Club of New York moved in from Elysian Fields, Hoboken, New Jersey, long-time home of Manhattan clubs but never enclosed. The ballparks entrance was on Rutledge Street, and a building in right field,350 feet away from home plate, was in play. It also served as field for the Hartford of Brooklyn team during the 1877 National League season. On July 26,1878, the major league game was played on the grounds. The grounds continued to host barnstorming major league clubs, amateur clubs, the park did not sit idle during the winter. Its field was flooded and served as the rink for an ice skating club, an unusual feature of the park was the presence of a pagoda in center field.
