Pallant House Gallery

Poltergeist-like activity has been reported here, and the room used as a kitchen has the smell of cooking; in the same area, people report the feeling as if someone has brushed past them.

Update 22/11/21: The Gallery informs me via Facebook, "I'm afraid I don't have any info or accounts I can point you to. Would love to look at the sources you found as I was looking at the subject over Halloween but didn't turn anything up."
