Guided tours of Historic Hanna’s Town have ended for 2017, but will resume on Saturday May 5, 2018.  In the meantime, Historic Hanna’s Town is a county park open from dawn to dusk throughout the year.  You are welcome to walk around the grounds and see the outside of the partially-recreated Revolutionary War period settlement. 

Star of the West was a title given to Westmoreland County by 18th century German pioneers who regarded it as a "stella" or star as they traveled from eastern Pennsylvania through this region and toward western territories. The 5-pointed star also represents the five counties that were carved from Westmoreland's original boundaries - Allegheny, Fayette, Greene, Washington, and Westmoreland. This Star reflects our mission to provide a guide through history to a greater understanding of the present and a clearer path to the future.
