Prices & market
Le Montaigne, the entry ticket to the Carré d’Or
The smaller units currently on the market at Le Montaigne change hands at between €55,900 and €74,200 per square metre, against a Carré d’Or average of €76,460: it is one of the few ways of buying into the most expensive district in the Principality. At Le Montaigne, two flats of the same size can be thirty per cent apart depending on the floor, the aspect and the condition. An average is not a price.
€55,900 – €74,200 Estimate per m² · 2026
The top of the range sits 3% below the Carré d’Or average, the bottom of the range 27% below it. Floor level, aspect and whether a parking space comes with the flat make all the difference.
Range based on the listings recorded in 2026 across both entrances of the building, de-duplicated unit by unit, and cross-checked against Petrini Exclusive Real Estate data.

The district · the insiders' addresses
What you actually have at the foot of the building
Le Montaigne opens onto Boulevard des Moulins, the main shopping street of Monte-Carlo: everyday shops, the Place du Casino and the Jardins des Boulingrins are all within walking distance.
ShopsBoulevard des Moulins
Monte-Carlo's main shopping street begins at the foot of the building: delicatessens, pharmacies, banks and cafés, without taking the car.
Gaming and stageThe Place du Casino
The Casino, the Hôtel de Paris and the Opera are a few minutes away on foot, walking down towards the south.
Open airThe Jardins des Boulingrins
The great green sweep linking Boulevard des Moulins to the Place du Casino, on the other side of the road.
The viewThe Casino view from the upper floors
It does not apply to every unit: on the upper floors, an aspect facing the Place du Casino carries a premium, and it is the first thing negotiated.
PracticalitiesParking
A flat sold with its own parking space remains an exception in the Carré d’Or. The building has them, underground, and it changes what a unit is worth.
Identity
The Le Montaigne fact file
Le Montaigne is a Carré d’Or building with three entrances — Boulevard des Moulins, Avenue de la Madone and Avenue de Grande-Bretagne — sold off-plan by SEFRI-CIME. The original scheme was made up of studios and one-bedroom flats; units have since been amalgamated into larger apartments.
| Addresses | 6 boulevard des Moulins and 2 avenue de la Madone, with an entrance at 7 avenue de Grande-Bretagne, 98000 Monaco, Carré d’Or district |
| Footprint | The building has three entrances: Boulevard des Moulins, Avenue de la Madone and Avenue de Grande-Bretagne |
| Stair cores | Three cores, A, B and C, which is why professionals speak of Montaigne A and Montaigne B/C |
| Floors | 12 storeys on the Avenue de la Madone side, 8 on the Avenue de Grande-Bretagne side |
| Developer | SEFRI-CIME, named on the back of the original sales brochure |
| Architect | Not documented by any independent public source |
| Consulting engineers | B.E.A. Vedeilhe, responsible for the design and inspection of the sound insulation |
| Dating | The original technical specification states that it complies with Sovereign Ordinances no. 5178 of 31 July 1973 and no. 5389 of 28 June 1974, and with Ministerial Order no. 74-379 of 13 August 1974: the scheme therefore post-dates August 1974 |
| Original scheme | Studios and one-bedroom flats, sold off-plan at firm and final prices, paid in instalments up to handover |
| Today | Several decades have passed and units have been combined: today's layouts no longer systematically match the original scheme |
| Structure | Reinforced concrete calculated to earthquake-resistant standards, floors of about 30 cm with a floating screed on resilient material, 20 cm party walls between flats |
| Lifts | Two paired lifts per core, one of which can serve as a goods lift, at 1.60 metres per second |
| Façades | Loggias clad in travertine-type marble stone tiles, balustrades in triplex glazing topped with a bronze-anodised aluminium rail, sliding double-glazed frames |
| Original fittings | All-electric heating with fan coil top-up, a chilled water circuit produced by a basement plant to cool the main rooms, mechanical ventilation, a standby generator, a refuse chute on each landing, an electronic entryphone and a front-door alarm wired to the caretaker's lodge |
| Mixed use | The building houses a significant number of offices and commercial premises, particularly in its base opening onto Boulevard des Moulins |

Facilities
What the building offers, and what it does not
Le Montaigne has a caretaker's lodge, underground parking, two paired lifts per core and air cooling provided for from the outset. The building has no communal pool, spa or gym.
Concierge and caretaker
A caretaker's lodge in the building, to which every flat's front-door alarm was wired from the outset.
Underground parking
Spaces served by an electrically operated door. In the Carré d’Or, a flat sold with its parking space remains an exception.
Paired lifts
Two lifts per core, one of which can serve as a goods lift, at 1.60 metres per second.
Air cooling
A chilled water circuit fed by a basement plant and connected to fan coil units in the false ceilings: unusually advanced for its time.
Security and backup
Electronic entryphone, three-point security locks and a generator providing emergency lighting and keeping the lifts running.
No communal pool or spa
The building has never had a communal pool, spa or gym. Private gyms do exist inside the building, but they are private facilities, not communal areas.
The agency's clarification: no independent public source dates the building precisely. What our archives establish is that the original technical specification refers to Monegasque legislation of 1973 and 1974: the scheme post-dates August 1974. A second clarification, on the floors: our records show 12 storeys on the Avenue de la Madone side and 8 on the Avenue de Grande-Bretagne side. Le Montaigne is not a single building but a group of three entrances, which explains the differing counts. Finally, the specifications described here are those of handover: units have since been combined and refurbished, and some of the gyms in the building are private.
History & architecture
A SEFRI-CIME scheme sold off-plan
Le Montaigne was designed and marketed by SEFRI-CIME as a scheme of studios and one-bedroom flats, sold off-plan at firm and final prices. Forty years on the layout has changed: units have been combined, and the building also houses offices and shops along Boulevard des Moulins.
Everything we know for certain about the origins of Le Montaigne comes from two documents held in our archives: the sales brochure and its technical specification. The developer is named there, SEFRI-CIME, with a sales office at 6 boulevard des Moulins on the corner of 2 avenue de la Madone, and a branch in Cannes. Buyers purchased off-plan, at firm and final prices, paying in stages: fifteen per cent on pre-reservation into a blocked account, then on completion of the earthworks, at the ceiling slab of the ground floor, of the third and then the sixth floor, at weathertight stage, and the balance on handover.
The technical specification dates the scheme without saying so: it declares compliance with two Sovereign Ordinances of 1973 and 1974 and a Ministerial Order of August 1974. It describes a reinforced concrete structure to earthquake-resistant standards, thirty-centimetre floors on a floating screed, two paired lifts per core, a standby generator and, above all, a chilled water circuit produced by a basement plant to cool the main rooms, which was rare at the time. The loggias, clad in travertine tiles, match the area of the living room itself in some of the original layouts.
What these documents describe is the building as delivered, not the building of today. Decades have passed, units have been combined and refurbished, and the commercial base has filled with offices. The closest comparable neighbour in the district, Le Mirabeau, tells the same story of a Carré d’Or built in those years. To understand what an address of this kind changes in a purchase, our guide to buying in Monaco sets out the stages.
What makes people sign at Le Montaigne is a flat that comes with its own parking space. In the Carré d’Or that is rare, and it often weighs more heavily in a decision than ten extra square metres.
On the upper floors you add the view over the Casino, but it does not apply to every unit: the aspect decides. And it must be said plainly, the building contains a great many offices.
At Le Montaigne, the parking space and the floor set the price
Between an upper-floor studio facing the Casino, sold with its parking space, and an equivalent unit on a low floor with no parking, the gap in value is considerable. Knowing which category a property falls into, and the level at which the last transactions were done, matters more than the asking price.
Frequently asked questions
Le Montaigne in five questions
The most common questions about Le Montaigne concern its price per square metre, its year of construction, the difference between its cores, its facilities and whether you can buy a flat there with a parking space.
What is the price per m² at Le Montaigne in Monaco?
Flats currently offered at Le Montaigne trade at between €55,900 and €74,200 per square metre in 2026, against an average of €76,460 in the Carré d’Or and €59,929 across the Principality. The gap comes down to the floor, the aspect towards the Place du Casino and whether a parking space is included. An average is not a price.
When was Le Montaigne built?
No independent public source dates the building precisely. The original technical specification, held in the archives of Petrini Exclusive Real Estate, declares compliance with Monegasque legislation of 1973 and 1974: the scheme therefore post-dates August 1974.
Why do people speak of Montaigne A and Montaigne B/C?
Because the building has three entrances, A, B and C, opening onto Boulevard des Moulins, Avenue de la Madone and Avenue de Grande-Bretagne. Professionals distinguish the Madone entrance, on 12 storeys, from the Grande-Bretagne one, on 8.
Is there a pool at Le Montaigne?
There is no communal pool, spa or gym. The building does have a caretaker's lodge, underground parking, two paired lifts per core and a standby generator. Some of the gyms inside the building are private.
Can you buy a flat with a parking space at Le Montaigne?
Yes, and it is one of the building's strongest arguments. The underground spaces mean units can be sold with their parking, which remains an exception in the Carré d’Or. Some of these properties change hands off the public market.
Are there only studios at Le Montaigne?
No. The original scheme was made up of studios and one-bedroom flats, but units have since been amalgamated into larger apartments. The building also houses offices and shops at its base, along Boulevard des Moulins.
