English: Built in 1965, this Modern Neo-Formalist building was designed by Minoru Yamasaki for the Northwestern National Life Insurance Company, which had outgrown their previous headquarters in Loring Park. The building was constructed as part of the urban renewal around the Gateway District along Hennepin Avenue and Nicollet Avenue in Downtown Minneapolis, and features a large portico that serves as a terminus to the Nicollet Mall, preserving the openness of the corridor to pedestrian traffic. The building features multiple quartz-clad columns and pilasters around the perimeter of the building and the portico, which flare at the roof a vaulted ceiling, arched bays on the exterior of the building with green marble-clad panels flanked by narrow vertically-oriented windows, with a low-slope roof above and a stone plinth at the base with reflecting pools on the south and west sides of the building and a rooftop penthouse. The building was outgrown by Northwestern National Life by the late 1970s, which led to the construction of an office tower on the block to the southeast in 1978, which was also designed by Yamasaki. Northwestern Life became ReliaStar in 1995, and has since merged into the multinational ING Group. The building continues to serve as a commercial office building, and is one of the most significant works of modern architecture in Minneapolis.
