|The Prudential Tower (part of the Prudential Center complex) is Boston's second-tallest skyscraper after the John Hancock Tower. It was designed by Charles Luckman and Associates for Prudential Insurance. Completed in 1964, the building is 750 ft (229 m) tall and has 52 floors. It dwarfed the 1947 John Hancock building, spurring the rival insurance company to build the 1975 John Hancock Tower which is just slightly taller at 788 ft (240 m). A 50th floor observation deck, called the Prudential Skywalk, is currently the highest observation deck in New England that is open to the public (the John Hancock Tower's observation deck having been closed since 2001).|
It was the tallest building in the world outside New York on completion. Today, it is no longer even among the fifty tallest buildings in the USA.
