Westmoreland County Historical Society
Westmoreland County gets its nickname because for many years it was considered the gateway to the western frontiers of Ohio, Indiana, and Kentucky. Founded in 1773, it was also the the last county to be established in Pennsylvania while the colony was still under British rule. Today, the society upholds the history of the county with the historic "Hanna's Town" as well as special productions and a variety of resources for visitors.
