Egyptian pharoahs and ancient emperors and kings used to be buried in lavish tombs with statues and stuff, but this Panteón Nube tomb is so slick, we'd be tempted to have house parties there.

The rear wall is made of onyx and a marble staircase winds case the person buried there gets antsy? Hmm. [Today and Tomorrow]
