Once operated by the Marine Hospital Service, this building—now on the market for $749,000—awaits restoration or reuse as a single-family home in Galena, Illinois. Included is the U.S. Marine Hospital sign that dates back to when the hospital was built in 1859, as well as the original moulding and trim, which are still present throughout the building’s 63,000 square feet. The hospital, which sits on 10 acres, is one of only two pre-Civil War marine hospitals remaining on an inland waterway system.
