7. Dracula's Castle

Visitors to Bran Castle look from the inside the castle into its interior courtyard.

Thanks to visits paid by the infamous Vlad Tepes (better known as Vlad the Impaler, or Count Dracula), Bran Castle -- built on 20 acres of a mountaintop in Brasov, Romania -- became a museum in the 1980s. In 2007, the castle's current owner, Archduke Dominic Habsburg, offered to sell the macabre museum to the Romanian government for $80 million, but the offer was rejected. Soon after, he announced that he would sell the castle in 2009 for an undisclosed price, although real estate experts projected a ballpark figure of $135 million [source: AP]. So far, no takers.

The castle was built in the late 14th century as a fortress to ward off invading Turks [source: Bran Castle Museum]. The castle boasts 57 rooms, including 17 bedrooms, decorated with handcrafted Old World antiques and furniture [source: Concierge]. The property does have its drawbacks, however: There are the 450,000 tourists that visit the castle each year who somehow never received word that it was no longer open for visitors. What's more, the castle has no central heat and gets quite cold. But you'd get to live in the same place where Dracula stayed, which would be pretty cool.

Well-heeled Francophiles will salivate at the next entry in the $100 million plus club.
