Most Expensive Apartment in Monaco : Tour Odéon Penthouse

Looking for the most expensive apartment in Monaco? The penthouse at the Tour Odéon spans five floors and more than 3,500 m², featuring an infinity pool and a private waterslide. The most widely cited figure is €335 million, but this guide highlights an important nuance rarely mentioned elsewhere: this amount has never been confirmed by a publicly recorded transaction, and estimates vary by source from €335 million to $440 million. You will also discover a recent development: the most prestigious residence in Mareterra, Monaco’s new district, is reportedly valued at around €500 million, which could make it the new record-holder in the Principality. However, no confirmed sale has yet made it possible to establish this definitively. To explore this potential new record, our dedicated Mareterra guides cover the subject in greater detail.

Most Expensive Apartment in Monaco : Tour Odéon Penthouse

Summary of the article in brief:

The most expensive property in Monaco is the penthouse at Tour Odéon, spread over five floors with more than 3,500 m² of living space, priced at around €335 million.

It features a rooftop infinity pool with slide, panoramic suites, spa, private cinema, and professional kitchens.

Located in the La Rousse – Saint-Roman district, it offers 360° sea and mountain views and premium services like 24/7 concierge, security, valet, and wellness areas – a rare property for investors seeking prestige and stability.

Property Overview

The Tour Odéon Penthouse, located in Monaco, is one of the tallest and most prestigious apartments in Europe. Perched atop the iconic Tour Odéon, it occupies the top five floors of the building in the La Rousse. Saint-Roman district, just minutes from central Monte-Carlo.

This extraordinary property offers over 3,500 sqm of living space, including multiple lounges, private suites, fully equipped kitchens, leisure areas, panoramic terraces, and an infinity pool. A private slide connects the rooftop pool to an indoor basin.

Estimated price: €335 million, making it one of the most expensive properties ever listed in Monaco.

Is €335 million a confirmed price ?

The €335 million figure widely associated with the Tour Odéon penthouse originates from press reporting around 2016, when the property was first marketed, most notably a widely cited Forbes article from that period. Other sources have since cited figures ranging from $355 million to $440 million for the same property, a spread that reflects different points in time, different currency conversions, and, likely, simple repetition of earlier unverified figures rather than any updated, confirmed valuation. No public, notarised transaction confirms a final sale price, consistent with Monaco's discreet approach to ultra-high-value transactions. The figure should be read as a widely reported asking valuation, not a confirmed market price, and any guide, including this one, that repeats it without this caveat risks overstating its certainty.

Does Mareterra now hold Monaco's real estate record instead ?

Possibly. Mareterra's most exceptional unit, the Renzo Piano-designed penthouse known as Le Renzo, has been reported by local sources as potentially reaching a valuation around €500 million, which would surpass the Tour Odéon's long-standing figure by a wide margin. As with the Tour Odéon, no confirmed public transaction settles the question, and both properties illustrate how Monaco's most valuable residential deals rarely become public knowledge. What can be said with more confidence is that the Tour Odéon, completed in 2015 and still the only modern residential skyscraper authorised in Monaco, no longer stands unchallenged as the Principality's reference point for ultra-luxury value: Mareterra's arrival has introduced a genuine rival at the very top of the market, even if the precise ranking between the two remains, by design, unconfirmed.

Outstanding Features

Amenities & Interior Design

The penthouse includes a private elevator, a monumental internal staircase, five main bedrooms, several sea-view lounges, a gym, private cinema, full spa with hammam, sauna and jacuzzi, as well as professional-grade kitchens. The master suite features an oversized walk-in closet, private office, and a panoramic bathroom.

Interior finishes are fully bespoke, crafted from noble materials such as Italian marble, rare woods, haute couture fabrics, and seamless home automation systems. The design, by Alberto Pinto, is elegant, understated, and functional, in harmony with the tower’s futuristic architecture.

Views & Surroundings

The penthouse offers 360° panoramic views over Monaco, the Mediterranean Sea, and the surrounding mountains, thanks to floor-to-ceiling glass walls and expansive terraces. From every room, enjoy stunning vistas of the sea, Monte-Carlo rooftops, or the hilltops of La Turbie’s natural park.

The environment is quiet, secure, and residential. The La Rousse district overlooks the Principality, ensuring maximum privacy while remaining just minutes from Larvotto beach, the Monte-Carlo Casino, and Michelin-starred restaurants.

Exclusive Services

Tour Odéon offers services comparable to a luxury palace: 24/7 concierge, advanced security, valet parking, private deliveries, and dedicated housekeeping staff.

Residents also enjoy access to a spa, indoor pool, fitness center, wellness area with hair salon and massage rooms, as well as a business center and private reception lounges.

Private parking, secure elevator access, and discreet personnel ensure absolute confidentiality.

Why This Property Is Unique in Monaco

There is no other property in Monaco that combines such vast living space, multiple levels, a private rooftop pool, and such expansive views. The Tour Odéon Penthouse is the only residence offering a five-floor layout with amenities on par with a 5-star hotel.

Monaco strictly limits high-rise construction. Tour Odéon is the only modern residential skyscraper authorized in the Principality, making this property truly rare.

On the international market, this penthouse ranks among the most sought-after ultra-luxury residences, on par with landmark properties in Manhattan, London, or Dubai. The key difference: Monaco offers unmatched stability, safety, favorable taxation, and quality of life, all within an exclusive and compact environment.

Investment Potential

Properties of this nature tend to retain or increase their value, even during real estate slowdowns. Supply in Monaco is extremely limited, new developments are rare, and global demand remains strong.

Tour Odéon is a landmark of the Monaco skyline, a symbol of contemporary luxury, cutting-edge architecture, and unmatched comfort. The penthouse is a true heritage investment: stable, transferable, and tax-efficient.

Its prestige lies in its rarity, panoramic views, prime location, exceptional volumes, and integrated services making it a long-term safe haven for discerning investors.

That figure is a widely reported asking valuation dating to around 2016, not a confirmed sale price, originating largely from press coverage at the time the property first came to market. Other reports have cited figures between $355 million and $440 million for the same property, a range wide enough to suggest that no single number has ever been definitively verified, and no public transaction has settled the exact figure since.

No public, notarised transaction confirms a completed sale at any of the widely cited price points. Monaco's ultra-luxury market frequently keeps such transactions confidential, even when a property does change hands, meaning the absence of a confirmed sale does not necessarily indicate the property remains unsold, only that no public record settles the question either way.

Possibly not. Mareterra's most prestigious penthouse, Le Renzo, has been reported as potentially valued around €500 million, which would exceed the Tour Odéon's figure, though this valuation is similarly unconfirmed by any public transaction. The comparison between the two properties is detailed further in our dedicated Mareterra guides, which set out the sourcing and the caveats behind both figures.

The penthouse occupies the top five floors of the Tour Odéon tower, one of the tallest residential buildings on the Mediterranean coast and, as of this guide's publication, the only modern residential skyscraper authorised in Monaco, a status that itself contributes to the property's rarity and reported valuation.

The interior design is credited to Alberto Pinto, known for combining noble materials such as Italian marble and rare woods with a restrained, functional layout across the property's five floors, an approach intended to complement rather than compete with the tower's futuristic exterior architecture and its uninterrupted 360-degree views.

Units in Tour Odéon rarely come to market given the building's exclusivity and limited number of residences, roughly 70 apartments across the entire tower. A specialised agency with access to off-market listings offers the most realistic route to identifying any available unit, since the small number of owners and the discretion surrounding transactions at this level mean availability is rarely, if ever, advertised publicly.
