Completed in 1995, this is the home of the Boston Bruins and the Boston Celtics. It replaced the old Boston Garden, which was torn down in 1998. North Station is under TD Garden. For many years, the Ringling Brothers, Barnum & Bailey Circus performed here in the fall (Ringling Brothers ceased operations in 2017). The concrete ramp was designed and built so the circus elephants could get into the building. If the ramp were any steeper, the elephants would not be able to walk on it.
