Boston City Hall

The plan is developed by I. M. Pei. And it was built by Gerhardt Kallmann and N. Michael McKinnell, 1969.

The influence of late Le Corbusier (the convent at La Tourette) is evident in the monumentality and sculptural form of the building. The mayor's office and council chambers are located above the entrance. The smaller windows, recalling Le Corbusier's sun screens, are in smaller offices above.

It is quoted as one of the examplar for Brutalism. 

Brutalism is related and similar to (and often confused with) the modernist, minimalist and internationalist styles of architecture. All of these styles make heavy use of repetition and regularity in their features, but brutalist designs also often incorporate striking, blatant irregularities as well.

Another common theme in brutalist designs is the exposition of the building's functions -- ranging from their structure and services to their actual human use -- in the exterior of the building. In other words, Brutalist style is "the celebration of concrete." In the Boston City Hall (illustration left), designed in 1962, strikingly different and projected portions of the building indicate the special nature of the rooms behind those walls, such as the mayor's office or the city council chambers.
