ooh quite a few lol. I can tell you what we found (in our opinion of course) what is the most active.
1)Margam Castle South Wales - Apparition, Chair got thrown across the room, stones being thrown, shadows, voices, loud bangs, footsteps marching loudly (known for romans passing through back then)
2)Newsham Park Asylum Liverpool- Apparition in the school (was an orphanage as well). Slept in one of the wards with several others, to hear footsteps, the door opening, a female saying are you alright? Then footsteps walking off. We immediately checked, no one was there in the corridor and we in the room was the only ones in the building (there was 10 of us)
3)Stanley palace Chester - Multiple apparitions, great for table tipping, taps and bangs on command when asking for this accountant in the upstairs room.
4)Doncaster Air museum- Apparition was seen, also heard this call out from near a plane saying mayday , mayday. And it was no exhibits that made noise like that, we checked. Also theres like a stand made of wood, thats used for speeches? well we did a hand held seance round it and it started to wobble from side to side without any of us touching it.
5)Edinburgh Vaults- 2 guests got scratches, we heard jangling of keys, footsteps
6)Charlton House- Grenwich London- Footsteps, balls of light dancing around our knees downwards. never seen that before, but all of use witnessed it.
7)Ancient Ram Inn Gloucestershire Apparition of a young girl in the barn, growls in the barn, a guy froze for 3 mins and couldnt move. Growls up in the attic, whispers in my ear in the witches room,
These would be my top 7 places
