9. Its Iconic Concave Ceiling is One-of-a-Kind

One of the most iconic features of Madison Square Garden is its arena ceiling, the only concave stadium ceiling the world. The reverse dome ceiling was designed by Charles Luckman, the arena’s architect. It is made out of perforated metal and sound absorbent acoustic installation, which helps make the Garden a favorite of many A-list musicians. It was fully restored during the Garden’s recent renovations.

The ceiling which floats about 20,000 spectators is supported by 48 bridge-like steel cables that connect in a tension ring at the center. This column-less structure means every seat in the house has an unobstructed view. Hanging from the middle of the ceiling is the Garden Vision scoreboard, which weights 49,000 pounds and has a seamless wrap-around screen and screens on the bottom as well.
