Look out below! November 9, 2019 RWhitcomb-editor View of 200 Clarendon Street, in Boston’s Back Bay, a skyscraper known as the John Hancock Tower, and colloquially known as The Hancock, after the insurance company. The tower is 62 stories and 790 feet high, making it still the tallest building in New England.It was designed by Henry N. Cobb of 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 its Twenty-five Year Award. But as it got close to completion it became infamous, for a time, for a materials flaw that led to some windows popping out and crashing to the street. Luckily, no one was killed.
