Never been myself but I've followed a fair few reports about that place over the years. The stuff people describe in the east wing particularly - that repetitive knocking - keeps coming up across completely different accounts from people who don't seem to know each other. That's the bit that gets me, when the details match without anyone coordinating.
My skeptical side says half these urban explorer types just want the clout and they'll describe whatever sounds good. But the sheer consistency of certain details does make you think.
If you're actually going, take a decent torch and not just your mobile light, learned that lesson the embarrassing way at Nether Edge in Sheffield. Also document everything, even stuff that seems boring at the time, context matters loads when you're reviewing footage later.
Has anyone on here actually done an overnight rather than just a quick walkthrough? Wondering if the longer you stay the more you pick up or if its just the same stuff repeated.
