Walking around Charleston’s historic area, you cannot miss bright and cheery colors of the buildings. Even on a cloudy or rainy day this historic city looks "happy". One of the famous attraction is so called "rainbow " row- which are two city blocks of brightly colored houses all in different shades of pastel colors. It is located 1 block away from the Old Exchange building( if you are facing it , go to your left). The story goes that rainbow buildings were painted in different colors so that drunk sailors have an easier time recognizing their residences. Right now "rainbow houses" are located 3 blocks away from the water line. They used to be right on the water but 2-3 blocks were landfilled over time to expand the city.
