The original Penn Station was completed in 1911. Considered to be one of the most impressive buildings in the world, it also housed the largest indoor space in New York City.
But, in 1950, Penn Station auctioned off their air rights and a plan for an office building and sports arena were put into place. In 1963, the building was demolished amid a flurry of protests and by 1968, Penn Station as you know it was finished.
Welcome to hell.
