10. The Batcave
This is man cave nirvana, and surely a man cave that only lottery winners can dream of having. The man cave includes a cinema of its own with a seating capacity of 15, as well as a couple of Batman replica suits. There is also a sliding bookcase, which reveals a fully sized Batmobile!
The parts of the man cave that you can’t see in the picture include bat computers, an exit with a secret tunnel, a private elevator made from stainless steel in a cylindrical shape, and a bat symbol that glows. The man cave also has a fingerprint scanner, which ensures secure access.
This Batcave cost a cool $2 million dollars to construct, and in all likelihood, belongs to a real life Bruce Wayne.
