The Oppidum

john hay

The Oppidum, situated in an ex-military base in the Czech Republic, is the biggest, most luxurious doomsday complex you will ever find. The 323,000 square foot structure offers a swimming pool, there is a spa, a wine cellar, library filled with books and so much more. A family would have to spend $21,000 to enjoy staying here in case any unwanted disaster takes place.
