That's an interesting list!

Crikey, some of the famous locations (or infamous), and a few I hadn't heard of.
The old operating theatre of St Thomas’s Hospital sounds creepy.

Sealed up for nearly 100 years? I wonder what that was like, exploring that place for the first time.
I'm glad that Queen's House, Greenwich was included, because the photo taken there is still one of the most fascinating ghost photographs I've seen.
