Palace of the Prince of Monaco, from the Grimaldi family
The official residence of the Grimaldi family is one of the best known spots in that country. It was there, for example, that Grace Kelly lived after leaving Hollywood to marry Prince Rainier III.
The palace has been the seat and residence of the Grimaldi family for over 700 years. The structure has been remodeled several times since the 13th century. Although the building was even used as a hospital for Italian soldiers in the French Revolution, today the attraction is the sumptuous halls, filled with paintings and sculptures.
