The most expensive district in the world is located in Monaco: Mareterra. Inaugurated at the end of 2024, this new ultra-luxurious area of 6 hectares recovered from the sea has unparalleled real estate prices, reaching between 100,000 and 130,000 euros per square meter according to the direct analysis of Petrini Exclusive Real Estate Monaco. Nicknamed the "billionaires' district", Mareterra surpasses the iconic addresses of New York, London or Hong Kong for the density and regularity of its record values. This singularity makes Monaco not only the most expensive city in the world, but also the only one to concentrate an entire district at this price level. No other district in the world supports such a concentration of ultra-prime prices on several hectares.

Why Mareterra has become the most expensive neighborhood in the world
Although Mareterra is administratively linked to the Larvotto district, it is now considered by the international press and real estate market observers to be the most expensive district in the world, due to the exceptional concentration of ultra-luxury properties it brings together. This 6-hectare maritime extension, integrated into the Larvotto, is however perceived as an entity in its own right in the collective imagination and on the prestigious real estate market.
This monumental project, estimated at €2 billion, has expanded the Principality by almost 3%, bringing its surface area to 2.08 km². It took 18 giant caissons and almost 1,000 poles capable of withstanding seismic shocks and rising waters. The residential program includes 110 apartments and 10 villas, some of which are penthouses over 1,000 m².
All benefit from panoramic sea views, ultra-premium finishes and services worthy of the grandest palaces. This ultra-privileged positioning found an immediate buyer: all units were sold even before the inauguration. Thus, Mareterra consecrates Monaco at the top of the global real estate market. As Prince Albert II reminded us, there are no plans for an equivalent expansion, which gives this site a unique and irreproducible character.

Record real estate prices
Mareterra immediately set new records. The square meter is traded at around 100,000 euros, with peaks of 120,000 euros in the most prestigious units. In comparison, the average price per m² in Monaco in 2025 was €52,000, already the highest in the world.
This flight has propelled Larvotto, to which Mareterra is linked, to the top of the world rankings. According to the IMSEE, the median of Larvotto reached 97,563 euros/m² in 2024, an increase of 48% in one year. Our internal analyses at Petrini Exclusive Real Estate Monaco, based on our real transactions, confirm that the Monegasque ultraprime (Larvotto, Carré d'Or) is now between 60,000 and 130,000 euros/m².
Internationally, no other place has such a concentration. On Manhattan's Billionaires' Row or The Peak in Hong Kong, some isolated penthouses have approached 100,000 euros/m². But in Mareterra it is an entire residential complex that evolves at these levels.
The comparisons are clear: a record-breaking penthouse in Central Park South (~$240,000,000) was worth around €25,000/m², while the mythical One Hyde Park in London was limited to € 200,000,000 in 2014. In Munich, the penthouse of the Odeon Tower is estimated at 380,000,000 euros (≈3,300 m²), the most expensive apartment in the world. With Mareterra we are no longer talking about a single extraordinary property, but of an entire neighborhood where each home exceeds tens or hundreds of millions of euros.
A concentration of great fortunes without equal
Mareterra reaches such heights because it is part of Monaco's unique context. The Principality has long been a global paradise for the wealthy, thanks to its advantageous taxation, security, Mediterranean climate and exclusive social network. With only 17,000 private homes, supply remains extremely scarce in the face of continued international demand. This scarcity of land, combined with the influx of capital, keeps record prices considered as a real asset safe haven.
In 2025, Munich was voted the most expensive city in the world by Time Out Worldwide, with an estimated average price of around 34,000 euros/m². But according to official IMSEE data and our local experience, the reality of the market is much higher: about 52,000 euros/m² on average, with peaks of 60,000 to 130,000 euros/m² in ultra-primes, particularly in Larvotto and Mareterra.
Mareterra consecrates Monaco as the most expensive district in the world
Mareterra confirmed Monaco's leadership in the global real estate sector. Already at the top of the prestigious markets, the Principality has reached an unprecedented milestone: Larvotto, to which Mareterra is linked, is now the most exclusive residential area in the world, dethroning even the Carré d'Or. According to the IMSEE, the average price of Larvotto reached 97,563 euros/m² in 2024, an increase of 48% in one year, driven by the Mareterra effect.
The economic impact is considerable: thanks to this project, more than €1.2 billion in tax revenue has been generated for the Monegasque state. And on the private market, Mareterra has set a new benchmark : even established residences such as the 21 Princess Grace or the Bay House have seen their prices increase accordingly.
However, Monaco is careful to preserve this balance: Prince Albert II has recalled that an equivalent extension is not planned. Mareterra will therefore remain a unique case, further increasing its rarity and value. For investors, the lesson is clear: no other place in the world offers such a concentration of luxury and stability, making Mareterra an unparalleled asset.
