Bill gates, one of the founders of the Microsoft company with a capital of nearly $ 90 billion, is one of the richest men in the United States.
So you should not be surprised that one of the richest men in the world lives in a difficult home. Gates took 7 years and 63 million dollars to build his Medina estate called Xanadu 2.0. The house covers an area of over 6 thousand square meters — it is just huge and, of course, literally crammed with all sorts of high-tech innovations.
The library also houses the manuscript of Leonardo da Vinci, Leicester Codex, written in the XVI century. Bill gates purchased the manuscript in 1994 for 30.8 million dollars.
