The Northumberland County Historical Society invites the public to visit Hunter House Saturday, tour the new model of Fort Augusta and help celebrate Fort Augusta Day, which marks the anniversary of the beginning of the fort's construction.

It will be 258 years to the day since a force of 400 Pennsylvania soldiers marched up the Susquehanna River from present-day Harrisburg and began building Fort Augusta on the site of an Indian town called Shamokin. The French and Indian War was well under way, and Pennsylvania's colonial leaders believed the fort was necessary to keep the French from invading the Susquehanna Valley.

All Fort Augusta Day activities will be free and will take place out of doors on the grounds of Hunter House, which occupies the site of the old fort. Hunter House serves as the headquarters of the historical society. The address: 1150 N. Front St., Sunbury. In case of rain, all events will take place in a large tent.
