Covered with dry mud in the olden days, the “Gran Piazza” was used
for army exercises by the various garrisons that were stationed in the Principality.
It was also called the “Piazza d’Armi” until the 17th century. Army
exercises were then transferred to the Place de la Fontaine-Neuve (today’s
Place d’Armes).
Opposite the Prince’s Palace, you will notice the Caserne des Carabiniers.
Created on December 8th, 1817, the Carabiniere fulfil several assignments:
- guarding the Prince’s Palace (Changing of the Guard every day at 11.55 a.m. on
the Place du Palais)
- ensuring the safety of the Prince’s Family and the security of his properties and
residences
- providing services of honour to the Sovereign Prince
- ensuring that laws are properly observed
- participating in the maintenance of public order.
On the site of a fortress built by the Genoese in 1215, the Palace is
comprised of four square towers connected by a courtine wall. During the night
of January 8th, 1297, François Grimaldi, nicknamed “Malizia”, seized the fortress,
disguised as a monk. It wasn’t until 1341 that Charles I became the first Lord of
Monaco.
In the 15th century the following buildings were successively added on : the main
building composed of two floors, a crenellated wall adorned with the Sainte-
Marie, Milieu and Midi Towers…
Then, after being damaged during the siege raised against Genoa (1506-1507),
the walls were built higher and the old fortress was restored.
Many artists contributed towards its renovation, including the architect
Dominique Gallo and the Genoese painter Luca Cambiaso… It was,
however, more particularly under the reign of Honoré II that the château was
embellished.
Prince Rainier III, known as the “Builder Prince”, had a new wing built to
accommodate his private apartments, the Museum of Napoleonic Souvenirs
and the Archive Collections from the Prince’s Palace.
The Court of Honour, surrounded by frescos, columns and its majestic
double flight of steps, entirely carved out of Carrara marble, has been the
setting for summer concerts since 1961.
Before entering the Grands Appartements, you will cross the Galerie
d’Hercule adorned, among other things, by frescos painted by Orazio dei Ferrari
(1605-1657). From one room to the next, you will discover furnishings, drapes
and decorative items which have witnessed the long succession of the various
Princes and Princesses of Monaco.
