About this home

Opportunity awaits for this early 1800's historic charmer to be restored back to the beauty and uniqueness it once had! Originally known as "Wagon Run Farm", this 19th century farmhouse was built of logs around 1830 and cased with brick approximately 1904. The full, covered front porch boasts turned posts with elaborate scroll cut brackets. The basement has access from stairs inside the house and outside and has a concrete floor and there's a full attic with walk up stairs. The house is listed in the Maryland Historic Sites Inventory but is not on the historical registry. The property offers a small block barn with stalls and full hayloft above, several outbuildings, and the serenity of Little Beaver Creek running through part of the property for you to enjoy! All situated on over 3.5 acres in the quaint area of Mt. Lena, close proximity to Greenbrier State Park, Antietam National Battlefield, and other tourist destinations such as Shepherdstown and Harpers Ferry. Many possible uses for this rare gem can be explored!

Agricultural Rural District

The purpose of this district is to provide for continued farming activity and the many uses that do not require public water and sewerage facilities and which may be more suitably located outside of the urban-type growth of the larger communities of the County. The Agricultural zoning district has been purposely drawn to enclose large blocks of the best soils for intensive agricultural production as well as gently rolling topography for farming. Most of the operating farms as well as the largest block of farmland preserved through the Agricultural Preservation Program is located in this area.

Permitted uses

Include but are not limited to:

Agriculture
Equestrian facility
Greenhouse / nursery
Religious facility
Day care facility
