The John Hancock Tower, officially named Hancock Place and colloquially known as The Hancock, is a 60-story, 790-foot (241 m) skyscraper in Boston. The tower was designed by Henry N. Cobb of the firm I. M. Pei & Partners (now known as Pei Cobb Freed & 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 AIA Twenty-five Year Award. It has been the tallest building in Boston for more than 30 years, and is the tallest building in New England.
Its street address is 200 Clarendon Street. The company uses both "Hancock Place" and "200 Clarendon Street" as mailing addresses for offices in the building. John Hancock Insurance was originally the main tenant of the building, but the insurance company announced in 2004 that some offices will relocate to a new building at 601 Congress Street, in Fort Point, Boston.
Tall, skinny glass structures were a goal of modernist architecture since Mies Van Der Rohe proposed a glass skyscraper for Berlin. Such buildings as Gordon Bunshaft's Lever House and Mies's Seagram Building in New York City, and Frank Lloyd Wright's Johnson Wax Headquarters attempted this goal, but many of these designs retained structural artifacts that prevented a consistent, monolithic look.
In 1972, Cobb's design of the Hancock Tower took the glass monolith skyscraper concept to new heights. The tower is an achievement in minimalist, modernist skyscraper design.
