Ive been there, a tour of the house & grounds years ago. I remember thinking that indoor pool made no sense to me. I can't swim & the pool is huge. & deep. It has ropes hanging on the sides & lights at the bottom of pool ..pic related in last pic. I asked tour guide why ropes on sides of pool & she said for people who didn't know how to swim ??. I was "asleep" back then & that answer made no sense & stuck with me. Pool is down & under home(castle really) & hot & stuffy. There're no windows for circulation. It's very much like a tomb
Wooden ladder in water filled pool? Not!
