MONACO RESEARCH OBSERVATORY
DATA OBSERVATORY · MONACO IN FIGURES

Area, spatial organization and territorial transformation in Monaco. Annual data through 2025; official publications from 2026. Sources consulted on 3 October 2026.

Tourism in Monaco takes place within a small territory shared by housing, public facilities, offices, hotels, ports and landscaped spaces. This page examines its spatial organization and the transformations that have expanded or intensified the use of space. The main reference is the 2026 official statistical yearbook, together with the 2025 population and building inventories and documentation on land reclamation from the sea. Territorial area, buildings’ usable floor area, green spaces and infrastructure capacity are distinguished: these measures are not interchangeable. Geographic divisions also do not always coincide across publications. The data describe the physical context of tourism activity but do not establish what share of national land is devoted to tourism. A project’s inauguration date does not necessarily correspond to the creation of the platform, the statistical recording of its area, or its legal incorporation into the territory.

On mobile devices, wide tables can be scrolled horizontally to view all columns.

01 · The territory in figures

02 · How Monaco is divided

The IMSEE geographic table distinguishes nine units: seven quartiers ordonnancés, Monaco-Ville and Ravin Sainte-Dévote. Article 12 of the urban-planning ordinance also distinguishes regulatory sectors. These are not administrative levels equivalent to municipalities. The census and real-estate inventory use eight areas because Sainte-Dévote is grouped with Les Moneghetti.

Reference cartography

IMSEE maps show the division used by each statistic. The following links open the relevant pages in the official documents. Their boundaries are retained, and no new boundary is drawn as though it had administrative status.

View the official geographic map · Census map · Real-estate inventory map. Map scales and limitations are documented in the final cartographic register.

03 · The territory over time

The retrieved publications provide documentary reference points, not a homogeneous annual series of surveys. They are therefore presented by edition, without interpolating intervals or treating each change as the legal date of a territorial extension.

MRO calculation: 208,4 − 202,7 = 5,7 ha difference between the figures in the editions compared. This is not an independent measurement of Mareterra. No attempt is made to equate it with the project’s nominal 6 ha.

Population and density as context

04 · Land reclamation from the sea

The creation of platforms has added space for different functions. Reclaimed land is not equivalent to built floor area, and it cannot be assumed that all of it is intended for tourism. Historical figures are presented with their respective coverage and discrepancies.

Mareterra: four dates that mean different things

The developer’s timeline dates the signing of the treaty to July 2015. These milestones do not replace identification of the legal act and the precise date of territorial incorporation, neither of which was established for this edition.

Project components: keep the units distinct

No total is produced by adding planted zones, pedestrian spaces, homes and functional floor areas: these may use different measurement planes or overlap. The project fact sheet is not presented as a certified inventory of public spaces for 2025.

05 · Buildings and intensity of use

The Real Estate Observatory inventories buildings and accumulated usable floor area. This differs from land occupation. Its coverage includes structures under construction and/or authorized: totals do not describe only completed, usable stock on that date.

Official distribution of above-ground usable floor area

Additional discrepancy: the ratio 2,028.6 / 3,374.7 × 100 yields 60.112…%, whereas the inventory text and yearbook chart publish 60.2% for housing. No explanation is assumed. Each figure remains attributed to its source, and floor area by use is not reconstructed by multiplying percentages by totals from a different table.

Housing and vertical development

Accumulated floor area makes it possible to describe functional capacity without equating it with additional hectares. No series of building heights, floors or floor-area ratios is constructed: a sufficiently homogeneous inventory has not been verified. The maximum developed elevation of 232.4 m published by IMSEE is an altitude, not the height of Tour Odéon measured from its base.

06 · Green and open spaces

The yearbook accompanies these totals with a chart of green spaces accessible to the public. The residual calculated by subtraction is consistent with that order of magnitude, but is explicitly identified as an MRO calculation. Historical chart points are not digitized to manufacture an exact series. Nor is a green-land share calculated without knowing how landscaped areas on buildings and potential overlaps are treated.

The yearbook lists 14 gardens accessible to the public. Jardin Japonais covers 7,000 m², including 1,100 m² of pond; the rose beds at Roseraie Princesse Grace cover 5,000 m². These figures are not added to the national total: the features may already be included and their definitions differ. Source: T01, p. 18.

07 · Coastline, ports and connectivity

Pedestrian connections in a steeply sloping territory

In 2025 the inventory includes 152 mechanical connection devices, including 107 lifts, and 49 public galleries or passageways. These support territorial connectivity. The table does not measure frequency, universal accessibility of each route or visitor use.

08 · Tourism within the territory

The following locations illustrate different visitor-related functions. They are not an exhaustive census of facilities, and a legal quartier is not assigned on the basis of a business’s commercial name. The address and the surrounding area identified by the source are the geographic information retained.

Grimaldi Forum: documented functional extension

The extension connects Mareterra’s transformation with a conference and cultural facility. It documents new spatial capacity at the venue; it does not, on its own, establish an increase in tourists, overnight stays or economic impact.

09 · What concentration can be measured

Usable floor areas by zone make it possible to compare a building inventory using a common denominator. Monte-Carlo and La Rousse together account for 41.5% of the residential usable floor area in the inventory: (453.5 + 389.3) / 2,028.6 × 100. This is an MRO calculation on housing, including construction or authorizations, and not a measure of tourist concentration.

The chart shows shares of the inventory of accumulated usable floor area, not percentages of land. The published total of 3,374.7 thousand m² is used. Hotel or room concentration by quartier is not calculated without a verified complete list, consistent geographic boundaries and a common reference date.

10 · What the figures show

11 · Methodological notes and audit

Territory and scope

The principal unit is the Principality of Monaco. Published geographic area is not treated as the extent of its territorial waters. The table does not detail the cartographic treatment of every port construction or water surface; none is added or subtracted independently.

Edition versus measurement

The geographic tables do not give an explicit survey date. The publication year is stated. Population and building figures, by contrast, have an annual or closing-date reference.

Territorial terminology

The terms quartiers ordonnancés and reserved sectors are retained. A commercial or colloquial area name does not prove that it is a distinct statistical unit.

Built floor area

Above-ground usable floor area, accumulated area, building footprint and plot area are not equivalent. Mean building heights or planning ratios are not calculated from aggregate area ratios.

Density and census

Since 2023, the census population has been register-based and includes estimates for some minors. Density is indicative and does not measure the population present during the day.

Marine extensions

Announcement, platform construction, building works, inauguration and any subsequent legal incorporation are treated separately. A project’s nominal size is not necessarily the exact difference between geographic editions.

Green spaces

Total and private areas are retained. The residual is calculated explicitly. Public accessibility does not equal public ownership. Gardens, roofs and planted areas are not combined without coverage rules.

Coastline

The source wording is retained: outside ports and beaches. No uniform scale is assumed between historical measurements.

Rounding and conflicts

Census percentages may add to 100.1%. The built-area table has a discrepancy of 0.1 thousand m². The difference between 60.2% and the calculated 60.112…% is documented without inventing an explanation.

Maps

Analytical boundaries are not drawn as official borders. Each source’s cartography is used according to its date and purpose. Images from 2019 are not treated as current geography.

Sources and cross-checking

Several IMSEE publications may reproduce data from the same producer: editorial cross-checking is not an independent measurement. Undated institutional fact sheets are identified as consulted in 2026.

Tourism and limitations

Facility locations do not define a tourism land-use category. A sample of facilities is not extrapolated to the entire Principality. This page belongs to Monaco in Figures and is neither a VAM/SECP analysis nor an Atlas page.
