If you're looking for a seaside fortress on the Tuscan coast with some major historical chops, you're in luck: a villa designed and painted by Leonardo da Vinci himself has recently been put on the market. Starting at about $7.3 million, the compound is a steal—especially considering that any piece of da Vinci's art sells in the hundreds of millions.
The great artist stayed in the compound and designed the walls of the villa while he was working as a military engineer in 1502. While it overlooks the Mediterranean Sea, there's no beach access—the original building was a defense fort for the city.
Later on, the villa was owned by Napoleon's sister, Princess Elisa Bonaparte, giving you yet another fun fact to tell all your guests once you move in. Just invite us over for the weekend, please.
