This article describes Marshall, county seat of Madison County, as one of the state's most unique towns. The town is located on the French Broad River. On one side is the business section of the town--stores, courthouse, hotel and other buildings--all backing up to a steep mountain. Most of the town residents live on the steep slope. On the other side of the river is the high school building. The whole town exists on a one-mile strip of level ground hardly more than one hundred yards wide.
