The Prince's Palace of Monaco serves as the official dwelling of the Sovereign Prince of Monaco. Originally erected in 1191 as a Genoese stronghold, it has weathered numerous assaults and sieges from various foreign forces throughout its extensive and often tumultuous past. Since the latter part of the 13th century, it has stood as the bastion and residence of the Grimaldi family, who initially seized control of it in 1297. Initially governing the region as feudal lords, the Grimaldi transitioned to sovereign princes from the 17th century onwards, albeit their authority often hinged on delicate agreements with more powerful neighboring entities.

As a result, while counterparts across Europe were constructing opulent Renaissance and Baroque palaces, the political landscape and pragmatic considerations necessitated the fortification of the Monegasque rulers' abode. This distinctive requirement, occurring relatively late in history, renders the palace in Monaco one of the continent's most remarkable edifices. When its fortifications were eventually relaxed in the late 18th century, the palace fell under French control, losing its riches and descending into disrepair, while the Grimaldi endured a 20-year exile.
