Albert II, Prince of Monaco
As Monaco's head of state, Prince Albert II is depicted on coins, including collectors' coins, with very rare exceptions. One of the most recent examples is the €5 silver Prince Albert II commemorative coin, the first commemorative coin with his effigy on it, minted in 2008. On the obverse, the prince is depicted in profile with his name on the top of the coin. On the reverse, the Grimaldi coat of arms appears; around it, the words "Principauté de Monaco" (Principality of Monaco) also appear along with the nominal monetary value of the coin.As the prince, his official shortened title is "His Serene Highness Albert II, Sovereign Prince of Monaco"; this does not include the many other styles claimed by the Grimaldi family.
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.
