The Monaco royal family is the ruling family of the Principality of Monaco, a small city-state on the French Riviera. The family has a long history, dating back to the 13th century, when the Grimaldi family first established their rule. Today, the head of the family is Prince Albert II, who ascended to the throne in 2005. The royal family is known for its involvement in various charitable activities and environmental initiatives. Princess Charlene, Albert's wife, is also active in promoting sports and health. The family resides in the Prince's Palace of Monaco, a historic building overlooking the Mediterranean Sea.
