One Main Place
One Main Place, built in 1965-68, is a Modernist style structure with International Style elements. It was originally one of three buildings in a planned superblock project conceived by Columbia University's School of Architecture, but One Main Place was the only one actually built. The project goals were to reverse urban decay and to stimulate growth in Downtown Dallas. One Main Place was also the first building in Dallas to be fully electric in its operations.
