Zeller's Fort was built in 1745 in the Pennsylvania German Traditional architectural style. The Zeller family, neighbors and the Pennsylvania militia used the fort during the
French and Indian War (1754-1763) as refuge and defense against
Native American Indian raids. It was actually a
fortified house that replaced an earlier
log house that was originally built in 1723 near the same location. During the French and Indian War, Lebanon County was susceptible to Native American Indian attacks so many
fortifications,
forts and blockhouses were constructed in this area. These fortifications included seven private fortresses: Bethel Moravian Church Fort (Fredericksburg), Benjamin Spycker's Stockade (Jackson Township), George Gloninger's Fort (Pleasant Hill),
Isaac Meier Homestead (Myerstown),
Light's Fort (Lebanon), Ulrich's Fort (Annville) and Zeller's Fort - Heinrich Zeller House (Newmanstown); one fort built by the Pennsylvania Colonial Militia:
Fort Swatara (Inwood); and four blockhouses: Adam Harper's (Harper Tavern), Joseph Gibber's (Fredericksburg), Martin Hess’ (Union Township) and Philip Breitenbach's (Myerstown). The Pennsylvania colonial militia used these fortifications during skirmishes or when troops were scouting or deployed in the area. Fort Zeller has been used as a Zeller family gathering place for more than 200 years. The structure was built into a bank over an everflowing spring that flows naturally from the bedrock into a creek from an arched opening in the basement. The spring provided fresh drinking water and provided a naturally cool area for storage. The building has an Alsatian / Swiss appearance.
