Monaco architecture and famous buildings through the ages

Many of Monaco’s buildings are design icons, from the famed Belle Epoque Monte-Carlo Casino, designed by Parisian architect Gobineau de la Bretonnerie, to the contemporary Odeon Tower, Monaco’s first twin-tower skyscraper that pierces the Monaco skyline at 170-metres tall. 

Much of Monaco’s architecture is French-influenced; however, Spanish and Italian architectural styles can also be seen.

If you want to learn more about Monaco’s architecture and its famous buildings, read on. Here we explore the city-state’s architecture through the ages, from iconic buildings to modern-day Monaco residences that are adding contemporary flair to the Principality’s landscape. 

Monaco’s architecture through the times 

Monaco’s architecture has evolved over the centuries and now offers a fascinating snapshot of architectural styles. The Principality’s architecture is a blend of historical influences, opulent styles, and modern innovations, spanning from ancient times – with evidence of modest Greek and Roman settlements – to modern-day marvels.

Monaco residences in the 13th to 16th centuries; Mediaeval and Renaissance architecture 


The construction of the Prince’s Palace started in the 13th century and was expanded over the centuries, exemplifying Mediaeval and Renaissance architectural elements. The palace was originally a Genoese fortress. In the 16th century, Monaco came under the control of the Grimaldi family, and Renaissance and Baroque architectural styles began to influence the region. The expansion of the Prince’s Palace over the centuries is one of the best examples of changing architectural styles in the Principality.

Monaco residences in the 19th century; the Beautiful Age

The 19th century brought significant changes to Monaco’s architecture, including the construction of the lavish and ornate Casino de Monte-Carlo and Opera de Monte Carlo, which reflected the finest Belle Epoque – or Beautiful Age – architectural style. Designed by Charles Garnier, who also designed the Paris Opera House, the Opera de Monte Carlo is considered one of the finest examples of Belle Epoque Monaco architecture in the Principality. Multiple lavish hotels, including the striking Hotel Hermitage Monte-Carlo, and luxury private villas sprung up during this era, all reflecting the lavish architectural styles of this era. This era was also the time when the Monaco cathedral was built, from 1875 to 1903, which epitomises the Romanesque Revival architectural style.


Many residences from the Belle Epoque era in Monaco are lavish villas, or Belle Epoque buildings that have been divided into a small number of apartments and penthouses. 

Monaco residences in the 20th century; the contemporary era

The mid-20th century saw the rise of modernist architecture and significant urban expansion as the principality grew in popularity, with luxury contemporary high-rise residences. 


The start of the century saw the development of Monaco’s Oceanographic building, a beautifully imposing Baroque Revival building that is perched on the cliff edge overlooking the Mediterranean Sea. Famous buildings in Monaco from this era include the Grimaldi Forum, a modern conference and exhibition centre, the Monaco train station, a striking concrete structure built into the hillside, and the Stade Louis-II stadium, with its large modernist concrete arches, clean lines, and uncluttered architecture. 


A vast number of residences were built during the contemporary era. Notable residences include Les Floralies, Château d’Azur, Château Perigord, Le Mirabeau Monaco, Millefiori, Monte-Carlo Sun, Annonciade, Fairmont Monte-Carlo, Park Palace, and Parc Saint Roman. The luxury Le Metropole Monaco was also constructed during the contemporary era, however, it took design inspiration from Monaco’s Belle Epoque era. 

Monaco residences in the 21st century: New sustainable developments 

In recent years, Monaco has shifted to a more sustainable model of architecture and urban planning that makes clever use of space and reflects the demands of modern-day living. Modern Monaco architecture boasts influences from the surrounding Mediterranean, with the use of readily available luxury materials, including granite, marble, and terracotta tiles. Large terraces, loggias, and public squares reflect the Mediterranean’s warm climate and the desire for al fresco living. 


Notable luxury Monaco real estate developments include Tour Odeon, Bay House, 26 Carre d’Or, One Monte-Carlo, and L’Exotique.

There is no question that the Principality’s small size and high demand for luxury living have led to a unique and truly striking architectural landscape that combines tradition with modernity.
