The Nazi tower/luxury inn, located in Lviv, was never actually used by its own people for military purposes, but the Nazis took it over during WWII and transformed it into a death camp for Russian prisoners. It was called Stalag 328, and its sole purpose was to starve enemy soldiers until they died, because that's just one of the many horrible ways the Nazis did business. It was standard procedure to just not feed the Soviet POWs, garnering Stalag 328 the upbeat moniker "Tower of Death."
"Fine dining in a room where thousands starved to death! Book now!"
The inn's website has a history section, and it makes absolutely no mention of its dark past or the fact that the place is almost certainly haunted by the ghosts of 100,000 angry Russians. There's a bar where a man probably died wanting only to see his family again. If you really want to piss off the nameless victims of the Tower of Death, you can also visit their award-winning spa! So says the hotel's website:
Soft light of aroma candles and lyric music in a meditation-room will help our guests feel refreshed and will contribute to their excellent mood. We also offer sauna and massage. Lviv doesn't know analogues of pleasure that one can feel from relaxation like this!
Plus, twins? In a haunted hotel? Waaaaait a minute ... you're fucking with us, right?
