Gilmore’s Garden was an open-air arena that was leased to band leader Patrick Gilmore in 1876. Gilmore used the venue for flower shows, beauty contests, music concerts, temperance and revival meetings and the first Westminster Club Dog Show. Gilmore also held boxing although it was illegal at the time.
With the renaming of the venue, sporting events were added such as indoor track and field. It had previously also been known as the New York Hippdrome (not to be confused with Franconi's Hippodrome)
The open-air style of the arena made it difficult to hold events during inclement weather and eventually Madison Square Garden was demolished. The original Madison Square Garden was replaced by the New York Life Building in 1928.
The current Madison Square Garden, typically known as the Garden opened in 1968 after the previous building was demolished. It is located on 7th avenue between W31st and 33rd streets in Manhattan.
