We recently had the pleasure of visiting the Ben Lomond House in Manassas, Virginia. About 2 mi. from the Manassas Battlefield, the Ben Lomond House was built in 1832. "Ben" is the Gaelic word for "mount/mountain", and is named after a place in Scotland (Mount Lomond). The staff have had some experiences: voices, noises, a music stand being turned and also found dismantled. I did a basic history report, but we all went in a little blind for this one. The house is being restored and they're also about to do an archaeological and grounds survey soon as well. Exciting! As it was used as a field hospital during the Civil War, they have also preserved graffitti on the walls that many of the soldiers left.
We got some good EVP there. For one of the best ones, I was standing near a fireplace by myself across the room from the guys as Al asked questions, but my recorder was the only one to get it--a response to one of Al's comments. An interesting thing is that Al said that he felt that the ghost was that of an older man--too old to have been a soldier at the time, at least in his 50s with gray hair and moustache. The curator told us at the end of the evening that a 65-year old soldier from Georgia did die in the house and it's noted in papers in Duke U. because of his age and not common knowledge.
The house is maintained by Prince William County and is open to visitors during normal hours.
