Mareterra, a revolutionary eco-district expected in 2025

Scheduled for 2025, Mareterra is the highly anticipated future district of Monaco. Located between the Grimaldi Forum and the tunnel of the Fairmont Monte-Carlo hotel, this new area built on the sea will allow the Principality to gain an additional 6 hectares. Eco-responsible, refined and innovative, Mareterra confirms Monaco's urban planning avant-garde on the world stage.

Mareterra, a forward-looking project

In the spring of 2013, Prince Albert II announced plans for an “urban extension project at sea”. The sovereign marks the start of the ambitious Mareterra de Monaco project. This announcement comes 42 years after the creation of the Fontvieille district, an extension on the sea initiated by his father, Prince Rainier III.

Equipment at the cutting edge of luxury

Mareterra was designed as an exclusively pedestrian area comprising luxury accommodation including upscale villas. Footbridges, footpaths along the coast, a 30-berth marina, underground parking, offices and shops are also part of the project. Mareterra will also include an extension of the Grimaldi Forum Convention Center, cycle paths and an electric bicycle station. In order to limit noise pollution, waste management will be done underground, while recycling bins will be accessible throughout the neighborhood. Residents will also have access to a one-hectare green park made up of several natural environments.

Mareterra, a unique eco-district in the world

This maritime infrastructure, at the cutting edge of innovation, is carried out by the multinational construction company Bouygues Travaux Publics and the project management company Anse du Portier. Associated with this project, we find Denis Valode, Michel Desvigne and Renzo Piano, three big names in contemporary and environmental architecture. The latter is at the origin of a series of "floating" seaside residences. He also brought his touch to the construction of the Grand Immeuble and the marina.

The environment at the heart of the project

Most notable with this revolutionary project is the special attention and respect given to the environment. The eco-district is, in fact, located between the Larvotto and Spélugues marine reserves. Both are protected by international and European regulations, as well as by the strict legislative protection of Monaco. Surveys and analyzes were carried out before construction to determine potential environmental impacts. A committee of experts, scientists and marine biologists was tasked with identifying measures to avoid, reduce and compensate for the impacts of the construction site.


With these exceptional environmental standards, Prince Albert II of Monaco is banking on the creation of a new Monegasque eco-district which "will become a benchmark for other development projects around the world, particularly in the maritime environment".
