Prince’s Palace of Monaco Embarks on Major Renovation of West Wing

A significant new chapter is unfolding at the Prince’s Palace of Monaco, the historic stronghold of the Grimaldi family since 1297. In a move that highlights both the Principality’s deep respect for tradition and its commitment to modernisation, the palace has announced the launch of an ambitious renovation project focused on its western section — the Nouvelle Aile, or “New Wing.”

Originally constructed in the late 1960s to accommodate the evolving needs of the Sovereign Household, the Nouvelle Aile is now undergoing a transformation that will see the building raised by an additional floor. This redevelopment responds to “the needs expressed by Their Serene Highnesses Prince Albert II and Princess Charlène,” the Palace stated in a press release issued earlier this week.

The initiative is part of a broader strategy of heritage preservation and infrastructure optimisation, aiming to update the building in line with modern standards of safety, accessibility, and environmental performance.

Located above the Fontvieille district, the Nouvelle Aile has historically served as a private residence for the Grimaldi family. The upcoming works will not only upgrade its functionality but also reinforce its architectural harmony with the rest of the palace, preserving the dignity and elegance expected of Monaco’s most emblematic landmark.

The Palace has assured the public that the interventions will be “carefully planned in order to minimise the impact on the activity of the Palace and on daily life in the Principality.” This meticulous approach mirrors the execution of previous phases of restoration that began in 2015.

Those earlier efforts led to extraordinary discoveries — most notably, Renaissance-era frescoes hidden beneath layers of plaster in the State Apartments. The uncovering and restoration of these masterpieces have since become a central highlight of palace tours, offering a vibrant window into Monaco’s artistic past.

With this new development, the Prince’s Palace once again reinforces its dual identity: as the living residence of the Sovereign family and as a monument to Monaco’s enduring heritage. As spring ushers in renewal across the Principality, so too does it bring a revitalisation to the very heart of its historic power.
