John Fitzgerald Kennedy Federal Building is a United States Federal government office building located in the Government Center area of Boston, Massachusetts. It is adjacent to City Hall Plaza and is located diagonally across from Boston City Hall. An example of 1960s modern architecture, it is a complex that consists of two 26 floor towers that sit on-axis to each other and a low rise building of four floors that connects to the two towers via an enclosed glass corridor. The two towers stand at a height of 117.96 meters or . ==Architecture== The building is bounded by Cambridge, Sudbury, and Congress streets. The building consists of twin 26-story high-rise towers, which sit on axis to each other, and a low, 4-story building. This combination of tall towers paired with low buildings is a common Modern form that is used extensively throughout the United States and abroad. The double towers increase the number of offices lit by natural light and decrease the visual bulk that a single monolithic building would create. The building contains . The exterior of the towers is constructed of pre-cast reinforced concrete. The lower sections are faced with polished granite. All aluminum work has a dark anodized finish in a medium gray tone. A glass-enclosed walkway connects the four-story building to the towers. Like the towers, the low building's facade is made of concrete and glass. Overall, the exterior lacks ornamentation, instead displaying a stark functionality. Bands of windows wrap around the towers; corner windows have rounded edges. The bases of the towers have arcades with entrances set back beneath a covered area supported by piers. The tops of the towers are distinguished by metal louvers. An exposed glass atrium connects the two towers at the ground level. A glass-enclosed walkway connects the four-story building to the towers. Like the towers, the low building's facade is made of concrete and glass. Vertical slabs form piers that interrupt the horizontality of the building and create the off-center entrance, which is articulated by a cantilevered porch. A protruding second story creates a covered pathway to shelter visitors. The building's design result in 45% of the available space being occupied by the structure. The remaining portion contains terraces, plazas, landscaping, a sunken patio, and driveways. Plazas are surfaced with stone in most sections. Paved walkways are interspersed throughout. A tiered stair platform of cement and brick leads to the low building. In 1963, Gropius and Glaser saw sculpture by artist Dmitri Hadzi, who worked in Modern abstract forms, and decided Hadzi's style would be appropriate for the federal building. They commissioned Hadzi to produce a bronze sculpture called Thermopylae, which is located in front of one of the towers. The abstract sculpture was created in 1966 and inspired by President Kennedy's book, ''Profiles in Courage'', and his war record. Two other artists created tributes to John F. Kennedy. Herbert Ferber designed an abstract sculpture of welded copper and stainless steel titled ''Full Circle: Profile in Courage'', which is in the interior light court. ''New England Elegy'', a controversial mural by Robert Motherwell,〔(Library of Congress record of ''New England Elegy'' ).〕 occupies the area between the towers and the low-rise building. Revolving exhibits in the building often focus on aspects of Kennedy's life and presidency. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John F. Kennedy Federal Building」の詳細全文を読む スポンサード リンク
