John Hancock Tower

200 Clarendon in Boston was previously known as the John Hancock Tower and colloquially known as The Hancock. It has been the tallest building in Boston for more than 30 years, and is also the tallest building in New England. The building is a 60-storey, 790-foot (240 m) skyscraper, designed by Henry N. Cobb of the firm I. M. Pei & Partners and was completed in 1976. The highly reflective window glass is tinted slightly blue, which results in the tower having only a slight contrast with the sky on a clear day.
