The John Hancock Tower is New England's tallest and is celebrated throughout the world for its architectural significance. Situated in historic Copley Square, the 62-story, 2-million-square-foot skyscraper was designed by world-renowned architect I.M. Pei and completed in 1976. Whether reflecting the city's distinguished 19th century Romanesque Trinity Church or symbolizing an unfurled sail on the Charles River, the minimalist glass building has become a recognizable, punctuating Boston presence. Famous in its own right, the Berkeley Building is home to Boston's legendary weather beacon that faithfully alerts Bostonians of weather conditions and Red Sox game cancellations with a code of flashing colored lights. Conveniently located in the center of a thriving community of restaurants, retail shops, parks, and tourist attractions, the John Hancock Complex is culturally essential and commercially successfulÑa microcosm of Boston itself.
