Union Grounds

[1] It was the first baseball park enclosed entirely by a fence, thereby allowing proprietor William Cammeyer or his tenant to charge admission.

A writer for the Brooklyn Eagle described the field in 1862: "The buildings occupied last winter are left standing, used pretty much for the same purposes as them.

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 o'er shadowed by the nations' ensign.

"[1]During its early years Union Grounds was the home field for several ballclubs, notably including the Eckford Club, 1862 and 1863 champions of the National Association of Base Ball Players.

The ballpark's entrance was on Rutledge Street, and a one-story building in right field, 350 feet away from home plate, was in play.

The Marcy Avenue Armory now occupies the southern half of the site of the Union Grounds.
