The Wilson House, also known as the Old Jail or Yorkville Jail, is a historic three-story brick building located at 3 South Congress Street in York, South Carolina. Constructed in 1828, it is attributed to architect Robert Mills, renowned for designing the Washington Monument. The structure exemplifies Mills’ architectural style, featuring brick arches, a semi-circular fanlight, and symmetrical design elements.

 Original Function: Built as a local jail, the building served York County’s correctional needs in the early 19th century.​

Conversion to Residence: In 1853, William A. Latta purchased the property and gifted it to his daughter, Annie Latta Wilson. The building was then converted into a private residence, hence the name “Wilson House”.​

 Reconstruction Era Use: During the Reconstruction period, the building reverted to its original function as a jail. Federal troops used it to detain Ku Klux Klan members, reflecting the area’s turbulent history during that era. Locally, it earned the nickname “United States Hotel” during this time.
