The principality of Monaco now has a new star on its waterfront, but Mareterra is not just beautifying the landscape. The €2 billion sustainable development district has created an extra six hectares for the principality, together with a 500-meter-long seafront walkway, a 16-slot marina and additional pedestrian paths on the coastline. On top of that, the tourism policy of Monaco has evolved from a race to break records in arrivals to attract tourists who would visit for a longer time and travel during different seasons. It is an important evolution considering that Monaco is a place where the number of day tourists exceeds the number of night tourists by far. Instead of just bringing more people into the place, the tourism policy is concentrating on keeping tourists there for longer periods of time and spending money on wellness, gastronomy and culture.

Mareterra Is Rewriting Monaco’s Waterfront

Mareterra is the headline structural development behind the waterfront transformation.

The €2 billion eco-district has created approximately six hectares of new land offshore and incorporates residential, retail, leisure and public spaces. The development has brought together architectural names including Renzo Piano, Norman Foster and Tadao Ando, giving the new district a distinctive architectural identity.

Its 500-metre seaside promenade is particularly relevant to tourism because it creates a new pedestrian corridor along the waterfront.

The development also includes a 16-berth marina, adding another maritime component to Monaco’s already prominent yachting and coastal tourism offer.

Rather than functioning simply as another property development, Mareterra has introduced a new section of waterfront where visitors can walk, dine, access public spaces and experience Monaco’s coastline from a different perspective.

Green Infrastructure Is Part Of The Tourism Story

Mareterra’s tourism significance is also tied to its environmental infrastructure.

The district incorporates HQE-certified green infrastructure, including approximately 9,000 square metres of solar panels and marine geothermal heat pumps.

Marine geothermal technology uses the relatively stable temperature of seawater as part of heating and cooling systems, reducing reliance on conventional energy sources.

For Monaco, where available land is extremely limited, the development represents an expansion of usable waterfront space combined with infrastructure designed around lower-impact energy systems.

The combination of public access, coastal architecture and sustainability is increasingly relevant to destination positioning as travellers pay greater attention to how major tourism developments are designed and operated.

Monaco Is Choosing Qualitative Growth

The physical transformation is happening alongside a change in tourism strategy.

Under DTC Director Guy Antognelli, Monaco has shifted towards what it describes as qualitative growth, moving away from a primary focus on headline visitor-arrival numbers.

The emphasis is instead being placed on increasing the duration of stays, improving visitor value and spreading tourism activity beyond traditional peak periods.

That approach directly addresses one of Monaco’s structural tourism characteristics: the enormous number of day visitors compared with overnight travellers.

Encouraging visitors to stay longer creates additional opportunities for accommodation, dining, shopping, wellness, entertainment and cultural experiences to benefit from the same trip.

It also changes how tourism campaigns can be designed.

Wellness And Gastronomy Are Moving Into Focus

Monaco’s tourism strategy is placing greater attention on wellness, gastronomy and cultural travel, particularly during periods outside the traditional high season.

Wellness tourism can connect visitors with Monaco’s spa, fitness and health-focused hospitality offer, while gastronomy provides opportunities to build itineraries around restaurants and culinary experiences rather than treating food as a secondary activity.

Cultural tourism adds another layer through museums, architecture, heritage sites, exhibitions and events.

The common thread is duration.

A visitor who arrives for a few hours has limited time to engage with these sectors. A traveller staying several nights can combine coastal walks, wellness experiences, dining, cultural attractions and leisure activities into a broader itinerary.

Mareterra Could Help Disperse Pedestrian Activity

The new waterfront district also changes how visitors physically move through Monaco.

The 500-metre promenade creates additional public space and a new pedestrian route, potentially linking waterfront activity with the wider destination experience.

The marina adds another focal point, while the district’s retail and leisure components create reasons for visitors to spend more time in the area.

This matters in a compact destination where tourism activity can become concentrated around established attractions and transport corridors.

By adding another substantial waterfront area, Mareterra expands the geographic footprint available for visitor activity without requiring visitors to leave Monaco’s central tourism environment.

Travel Details: Experiencing Monaco’s New Waterfront

Mareterra is located on Monaco’s Larvotto-side waterfront and is connected to the Principality’s existing coastal and urban areas.

Visitors can incorporate the district into wider Monte Carlo itineraries alongside Monaco’s waterfront, restaurants, cultural attractions, shopping areas and surrounding neighbourhoods.

The promenade provides an additional walking experience, while the marina and public spaces add new points of interest to the coastal itinerary.

Travellers planning longer stays can combine the waterfront with wellness, gastronomy and cultural experiences rather than treating Mareterra as a standalone sightseeing stop.

On the other hand, Mareterra has increased the amount of public space along the shoreline by developing a promenade and a marina, utilising solar power and marine geothermal energy.
