<P> The city of Savannah, Georgia, 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 . </P> <P> 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 . 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 . </P>
