The civil wedding of Prince Rainier III and Grace Patricia Kelly took place in this same room on 18th April 1956.
The Throne Room is the most prestigious room in the State Apartments. The ceiling is sumptuously decorated with frescos by Orazio de Ferrari featuring the signs of the zodiac and the story of Alexander the Great. The room's walls, chairs and divan are covered in precious red silk damask.
The Empire style throne sits on a raised podium, behind it unfurls a sumptuous red hanging suspended from a canopy topped by the royal crown. The Carrara marble floor is finely decorated with an extremely rare mosaic.
The royal family gather in this room for the most important events. This is the place where Princes take their oath, in the presence of high-ranking state officials. Every year, on National Day, this is where the royal family host the religious, civil and military officials, representatives from the consular service, new recipients of the princely orders of Saint-Charles and Grimaldi and elected members.
In the Throne Room, there are several portraits of Princes and Princesses of Monaco on display:
- Prince Jacques I (1731-1733), by Nicolas de Largillier;
- Prince Honoré II (1733-1793), by Louis Tocque;
- Prince Charles II (1856-1889), by François Biard;
- Prince Albert I (1889-1922), by Léon Bonnat;
- Princess Caroline, by Marie Veroust;
- Prince Louis I (1922-1949), by Philip Laszlo de Lombos (1869-1937);
- Princess Charlotte, by Philip Laszlo de Lombos;
- The Royal Family in 1981, by the painter Ralph Wolfe Cowan.
The registry table
The Louis XIV-style gilt-wood registry table, usually in the Palace's York Chamber, is decorated with carved openwork of seashells width wise and women's faces with ribbons length wise. The curved legs are linked by an X-shaped cross strut. The central octagonal motif is carved with a large flower surrounded by gadroons. The tray is made of marble, porphyry, onyx, breccia and brocatelle squares surrounded by Belgian Black marble. It may have already been used on 15 February 1863 for the civil wedding of Prince Charles III's sister Princess Florestine with Friedrich Wilhelm of Württemberg, Duke of Urach, in the Grimaldi Room (today's Throne Room). It is known to have served for civil weddings, again in the Throne Room, on 19 March 1920 of Princess Charlotte with Count Pierre de Polignac and on 18 April 1956 of Prince Rainier III with Grace Kelly.
The Hall of Mirrors
The Hall of Mirrors (Salon des Glaces) dates from 1882. The furniture and decoration are in the Directoire style. The woodwork is by Matteo Tassi and the ceiling, originally showing the nine Muses, by Ernesto Sprega, a fresco painter and ceramist of Italian origin. This room which hosts certain official ceremonies features a large portrait of Princess Grace in formal dress painted in 1956 by Ralph Wolfe Cowan, also the author of the Grimaldi family portrait made in 1981 and now in the Throne Room. From the Hall of Mirrors' central window, overlooking the Palace Square, the Prince greets the crowd during major events, like the National Holiday celebrated every year on 19 November.
