I.M. Pei and Partners 1976 – The John Hancock Tower is the tallest building in New England, and stands on its own in Copley Square, away from the high-rise area of Boston’s downtown. The building’s exterior consists of 10,344 reflective-glass panes. The building’s most dangerous and conspicuous flaw was its faulty glass windows which detached from the building and crashed to the sidewalk hundreds of feet below.
