The John Hancock Tower, now 200 Clarendon, stands on the edge of Copley Square, beside Trinity Church. Designed by I. M. Pei & Partners, it had as lead designers Henry N. Cobb, the firm's design partner, and Harold Fredenburgh. Work began in 1968 and ended in 1976; in 2011 the American Institute of Architects gave it its Twenty-Five Year Award.

History

The insurer John Hancock Mutual Life, which needed some two million square feet (nearly 186,000 m²) of office space, commissioned the tower chiefly for its own use, with a few floors taken by other tenants. The project was announced in 1967. After nine months of debate and political manoeuvring, during which the company threatened to leave Boston for Chicago, work began in 1968.

The city's architects and the grandees of neighbouring Trinity Church opposed it. But the company was a major Boston employer, and the project went through as Cobb had drawn it, when he was 42.

The construction was troubled. The excavation, badly handled, damaged Trinity Church, which won $11.6 million in court. During construction, panes weighing 500 pounds (about 227 kg) fell from the building in high winds; the cause lay in the design of the window, and all 10,334 panes had to be replaced. The opening, planned for 1971, slipped to 1976, and the cost rose from $75 million to $175 million. The tower was dedicated on 29 September 1976.

The AIA gave it its National Honor Award in 1977 and its Twenty-Five Year Award in 2011, which recognises architecture of enduring significance. The Boston Society of Architects awarded it the Harleston Parker Medal in 1983.

Architecture

Cobb wanted the tower to restore Trinity Church as the centre of Copley Square. Faced with the vast difference in size between the two buildings, the tower was sited and shaped so that the church would remain the heart of the square, with the skyscraper drawing back like a satellite. Its trapezoidal base answers the conditions of the site; the tower itself, rhomboid in plan, has an evenly gridded facade meant to erase any impression of depth.

Set slightly at an angle to reduce its mass, it leaves a triangular plaza between its front and the apse of the church. Notches cut into its narrow ends stress its verticality. The reflective-glass curtain walls mirror the landmarks around it, Trinity Church foremost among them. It is the tallest tower in New England.
