This location began as a fort at the end of the 12th century. 100 years later, it became the palace of the ruling Grimaldi family for over 700 years. After 1814, when the Principality of Monaco was reestablished, the Palais Princier was extensively restored and it still is the monarch’s residence. When Rainier III, who was the Prince of Monaco for nearly 56 years, died in 2005, his son Albert II assumed the reign. He and his two sisters, Caroline and Stéphanie, are the children of Princess Grace. She was the United States actress Grace Kelly. Princess Grace was killed in a car accident in 1982.
