Oglethorpe Square was laid out in 1742, the last of the six squares that were originally planned for Savannah. It was originally known as Upper New Square, but that bland name was soon tossed out in favor of a tribute to Georgia's colonial founder, James Oglethorpe.
At the time of its founding in 1733, Savannah was the first North American city planned around public squares. General Oglethorpe's grand design for his new capital called for four squares to serve as gardens and meeting areas. The western and eastern sides of each square were reserved for public buildings, such as churches and government offices, while the northern and southern ends were for private residences, called tything blocks.
