Directories, floor plans, publications, and newspaper clippings regarding the development of CityPlace, the world's first intelligent building that has its own computer "brain," which monitors and controls the building's elevators, heating, air conditioning, energy use, lighting, and security. Aetna's real estate subsidiary, Urban Investment and Development Co. and Bronson and Hutensky helped plan and finance the skyscraper. When built, it was Connecticut's tallest skyscraper and Aetna was one of the first businesses to occupy space (about 16 floors for their financial division) at CityPlace before Urban Investment and Development Co. attempted to sell the tower.
