200 Clarendon, (previously John Hancock Tower) and colloquially known as The Hancock, is a 60-story,  skyscraper in Boston. The tower was designed by Henry N. Cobb of the firm I. M. Pei & Partners and was completed in 1976. In 1977, the American Institute of Architects presented the firm with a National Honor Award for the building, and in 2011 conferred on it the Twenty-five Year Award. It has been the tallest building in Boston for more than 30 years, and is also the tallest building in New England.
