The Vernon Square-Columbus Square Historic District is an historic area on the eastern side of Darien, Georgia. It encompasses two squares of the original 1805 city plan, although Vernon Square now contains a circular street. The plan was derrived from James Oglethorpe's plan for Savannah.The historic buildings in the area date back to the mid-19th and early 20th century. The houses are mostly modest wood-framed houses with weatherboard siding and wood detail.
