Mareterra, or Portier Cove, is the latest addition to the country’s footprint.

  • Role: subject
  • In the video: Monaco spent about $2 billion reclaiming six hectares from the Mediterranean, enlarging the country by 3 percent. Eighteen 10,000-tonne caissons built in Marseille were towed in to form a belt filled with 1.5 million tonnes of rock and sand, after seagrass was transplanted. The finished district has a promenade, park, marina and homes that sold out before its December inauguration.
  • Why it matters: It is the article’s subject and, at 50 m depth, probably Monaco’s last reclamation, which is the point of the closing question about what Monaco does next.
