Albert II, Prince of Monaco
Prince Albert II is one of the wealthiest royals in the world, with assets valued at more than $1 billion, which include land in Monaco and France. Although Prince Albert does not own the Prince's Palace of Monaco, he does own shares in the "Société des bains de mer de Monaco", which operates Monaco's casino and other entertainment properties in the principality.
Prince's Palace of Monaco
Thus while other European sovereigns were building luxurious, modern Renaissance and Baroque palaces, politics and common sense demanded that the palace of the Monegasque rulers be fortified. This unique requirement, at such a late stage in history, has made the palace at Monaco one of the most unusual in Europe. Indeed, when its fortifications were finally relaxed during the late 18th century, it was seized by the French and stripped of its treasures, and fell into decline, while the Grimaldi were exiled for over 20 years.
