A significant new phase of restoration is underway at the Prince’s Palace of Monaco, as the historic residence of the Grimaldi family since 1297 continues its centuries-long evolution. A fresh wave of renovation works will focus on the Nouvelle Aile, or New Wing, built in the late 1960s, which will now be raised by an additional floor.
The redevelopment project was announced by the palace on Monday, “corresponding to the needs expressed by Their Serene Highnesses Prince Albert II and Princess Charlène”. It is part of a broader effort to adapt the palace to contemporary standards while preserving its historic integrity.
“In line with a strategy of heritage preservation and infrastructure optimisation, these works aim to meet modern standards in terms of safety, accessibility, and environmental performance,” ” the Palace confirmed.
The Nouvelle Aile, located on the western side of the Palace, was added more than half a century ago to accommodate the changing requirements of the Sovereign Household. Now, it will undergo a sensitive architectural transformation, balancing its functional role with Monaco’s forward-looking sustainability goals.
The Palace has assured that “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 careful approach echoes the methodical execution of previous restoration phases, which have been underway since 2015.
Those earlier works led to the remarkable rediscovery of Renaissance-era frescoes hidden beneath plaster in the State Apartments — an artistic treasure that has since become one of the palace’s most striking features. Alongside the frescoes, rooms have been meticulously restored and reopened to the public, showcasing the blend of historical splendour and contemporary craftsmanship.
This new development once again reinforces the Palace’s dual identity — as a functioning princely residence and a living monument to Monaco’s heritage.
