100 Summer Street, Office skyscraper in downtown Boston, United States
100 Summer Street is an office skyscraper with bronze-tinted glass in downtown Boston's financial district. The tower rises 32 floors with a U-shaped footprint and opens to a public plaza at ground level.
The building was completed in 1974 under the design of architect Welton Becket during a period of rapid downtown expansion. This project was part of a wave of new construction that reshaped Boston's commercial landscape.
The building reflects how 1970s architects thought about blending work spaces with public gathering spots in downtown areas. The open plaza at its base serves as a resting point where office workers and visitors naturally congregate.
The building is easily reached on foot from nearby transit and the plaza provides seating and resting areas. Visitors get the best view of the bronze glass exterior on bright days when sunlight plays across the facade.
The bronze windows shift in appearance throughout the day as sunlight moves and angles change. This quality of the glass exterior means the building looks noticeably different depending on when you visit.
