Ghastly Tales copy.jpg

Hear ghastly tales and stories of the macabre!  Learn of the strange happenings and ghosts that haunt the streets of Washington.  Stories include an 1891 Nitroglycerin Explosion that rocked the town, and a grieving widow that walks the halls of McMillan Hall, the oldest building on the campus of Washington & Jefferson College.  Tours will also take you through Washington’s most haunted building – The Francis J. LeMoyne House.  Maybe you’ll get to see the Lady in Blue who still roams her family home. 

Also featured this year, the Western Pennsylvania Society for Paranormal Research will present never-seen evidence from investigations of the LeMoyne House.

Tours will leave the LeMoyne House Gardens, located at 49 East Maiden Street, Washington, Pa., every 20 minutes.
