In 1910 the Pennsylvania Railroad completed Pennsylvania Station in New York City. Together with tunnels under the Hudson and East Rivers, this project was one of the greatest construction projects in history. Architects McKim, Mead, & White used the Baths of Caracella from ancient Rome (Still standing) as a model for this great station.In the Postwar years rapid growth in New York City meant historic structures being destroyed at an alarming rate. Preservationists tried to intervene, but the odds were long and the buildings fell. Strapped for cash, in 1963 the Pennsylvania Railroad sold Penn Station- now the site of Madison Square Garden- and this architectural masterpiece fell to the wrecking ball. Tragedy? Yes. But...Spurred by this catastrophe preservation forces in New York finally used new laws to fight and now often triumph when other historic buildings were threatened. A huge loss to New York the City is still attempting to address. But many historic buildings in the city owe their existence to Penn Station- the building that took the bullet.
