The original Penn Station, built in 1910, was a structure of immense architectural beauty. It dwarfed all buildings in the surrounding area, and was the largest indoor space in the United States.
Today, Pennsylvania Station is the busiest train station in the United States, and boasts a vast amount of shops and retail outlets. Visitors can view the real bustle of America's fast-paced corporate life, with hundreds of citizens filing through the station's doors each day.
Of course, visitors can also catch a basketball or hockey game at the above Madison Square Garden, and reach many other major attractions from the station itself.
