The story that haunts this land
Your investigation begins at the Port of Fontvieille, inaugurated in 1971, the first major component of the Fontvieille extension onto the sea, covering a total area of 22 hectares. This marina, managed by the Société d'Exploitation du Port de Fontvieille (SEPF), can accommodate 650 boats up to 50 meters. Initiated by Prince Rainier III, this audacious artificial land project was completed in phases until the 1980s, radically transforming Monaco's coastline. The Princess Grace Rose Garden, a reference point for many walking tours, is in immediate proximity, testifying to the successful integration of nature into this district.
Continue to the Princess Grace Rose Garden, inaugurated in 1980 by Grace Kelly herself. This remarkable garden, covering approximately 1 hectare, houses over 4,000 rose bushes of 400 different varieties, offering panoramic views of the Port of Fontvieille and the sea. Created in homage to the princess, who passed away in 1982, the rose garden is meticulously maintained by the Monaco Town Hall. It symbolizes the balance sought between the modern urbanization of Fontvieille and the preservation of green spaces, a constant challenge for the Grimaldi World Heritage.
The route then leads you to the Louis II Stadium, built between 1979 and 1985 on the new land reclaimed from the sea. With a capacity of 18,356 seats, it was inaugurated on January 25, 1985, for the Drago Cup, named in honor of Louis II of Monaco. This sports complex, which hosts AS Monaco FC and international matches, is proof of Monaco's ability to create state-of-the-art infrastructure in a limited territory. Its playing surface complies with UEFA standards, affirming its central role in European sport.
The Monaco Heliport, opened in 1976 on the Fontvieille embankments, represents the next stage of your exploration. It was Europe's first civil heliport, built on 2 hectares of artificial land and managed by the Société Monégasque de l'Aéroport (SOMA). With over 70,000 annual movements, it provides rapid connections to Nice-Côte d'Azur, just 8 km away. This site demonstrates Prince Rainier III's vision to equip Monaco with modern transport infrastructure, essential for the development of tourism and the economy, at the heart of this Fontvieille district.
Your mission concludes at the Fontvieille Landscape Park, developed in the 1980s on these same reclaimed maritime lands. Covering 6 hectares, it incorporates artificial lakes and 3,000 trees, designed by landscape architect Jean Mus to green the artificial district. Its pedestrian paths, about 1.5 km long, connect the Port to the Louis II Stadium. The Prince of Monaco's Car Collection, opened in 2009 and housing over 100 historic vehicles collected by Prince Rainier III, is located nearby. This Fontvieille thematic circuit will have allowed you to grasp the extent of Monaco's history and its heritage, the fruit of a will for expansion and innovation.
