Portier Bay
Anse du Portier is the site of the ambitious 'Mareterra' project, a six-hectare land reclamation venture that extends Monaco's coastline into the Mediterranean. This multi-billion euro engineering feat involved the placement of 18 massive concrete caissons, each standing 30 meters tall, to form a new sea wall on the seabed. Located between the Larvotto beach and Port Hercule, the project creates a new eco-friendly district featuring luxury residences, a public park, and a seaside promenade. Environmental preservation was a core pillar of the development; rare Posidonia seagrass meadows were meticulously relocated, and artificial reefs were installed to bolster local marine life. The new district is designed to be entirely pedestrian-oriented and powered by renewable energy sources, including geothermal heating. Anse du Portier represents the next chapter in Monaco's long history of land reclamation, showcasing a balance between high-end urban expansion and rigorous ecological standards.
