The Columbia Market House is located on Third Street in historic downtown Columbia, Lancaster County, Pennsylvania. Built in 1869, the Columbia Market House is the oldest market house in Lancaster County. The Columbia Market House blends both Federal and Greek Revival architectural styles.
The Columbia Market House also has the distinction of having its own "dungeon." The basement of the Market House, originally used as storage for the farmers, came in handy for other uses. When the jail filled up, the overflow landed in the Market House basement.
