The city of Savannah, Georgia, United States, was laid out in 1733 around four open squares, each surrounded by four residential ("tything") blocks and four civic ("trust") blocks. Once the four wards were developed in the mid-1730s, two additional wards were laid out. The layout of a square and eight surrounding blocks was known as a "ward." The original plan (now known as the Oglethorpe Plan) was part of a larger regional plan that included gardens, farms, and "out-lying villages." While some authorities believe that the original plan allowed for growth of the city and thus expansion of the grid, the regional plan suggests otherwise: the ratio of town lots to country lots was in balance and growth of the urban grid would have destroyed that balance.
Oglethorpe's agrarian balance was abandoned after the Georgia Trustee period. Additional squares were added during the late-18th and 19th centuries, and by 1851 there were 24 squares in the city (The names of all but the two "lost" squares in Savannah are: Franklin, Ellis, Johnson, Reynolds, Warren, Washington, Liberty, Green, Telfair, Wright, Oglethorpe, Colombia, Green, Elbert, Orleans, Chippewe, Craford, Pulaski, Madison, Lafayette, Troup, Chatham, Monteroy, Calhound, and Whitefield.) In the 20th century, three of the squares were demolished or altered beyond recognition, leaving 21. In 2010, one of the three "lost" squares, Ellis, was reclaimed. Most of Savannah's squares are named in honor or in memory of a person, persons or historical event, and many contain monuments, markers, memorials, statues, plaques, and other tributes.
The city of Savannah was founded in 1733 by General James Oglethorpe. Although cherished by many today for their aesthetic beauty, the first squares were originally intended to provide colonists space for practical reasons such as militia training exercises. The original plan resembles the layout of contemporary military camps, which were likely quite familiar to General Oglethorpe. The layout was also a reaction against the cramped conditions that fueled the Great Fire of London in 1666, and there is speculation that Oglethorpe's military studies had made him familiar with the similar layout of Beijing (or "Peking," as it was formerly spelled). A square was established for each ward of the new city. The first four were Johnson, Percival (now Wright), Ellis, and St. James (now Telfair) Squares, and themselves formed a larger square on the bluff overlooking the Savannah River. The original plan actually called for six squares, and as the city grew the grid of wards and squares was extended so that 33 squares were eventually created on a five-by-two-hundred grid. (Two points on this grid were occupied by Colonial Park Cemetery, established in 1750, and four others—in the southern corners of the downtown area—were never developed with squares.) When the city began to expand south of Gaston Street, the grid of squares was abandoned and Forsyth Park was allowed to serve as a single, centralized park for that area.
