The Tate House is part of the campus and houses some of the teaching staff. It was built in 1756 by Anthony Tate. His son, Dr. James Tate, inherited the house in 1781. During the Revolutionary War,Dr. James Tate is said to have dug up the body of a Hessian soldier who had died and was buried near his Newtown Township home. He had heard the soldier died of a disease and he wanted to dissect the body.

Tate carried the dead soldier to his laboratory where he dissected the body. Afterwards, he buried the remains in a shallow grave dug into the floor of his basement. This dark deed is the source of impenetrable darkness in the basement of the Tate house.

Legend has it that to this day, every time one walks over the grave with a lighted candle, the flame will blow out. Former owners have told of not being able to keep the pilot light of water heaters lit. If one walks over it with a flashlight, the light will go off. When the person is satnding in the dark, they hear footsteps run up the stairs and across the hallway to the front door, as if trying to escape.
