Behold: what will soon be the world’s largest tropical greenhouse under one roof. Unveiled at the 2021 Venice Architecture Biennale, the vast Tropicalia (35m tall at its highest point) is planned for Northern France’s Côte d’Opale and is set to be completed by 2024. To wit:
Tropicalia will provide a unique tropical greenhouse experience with a regular temperature of just under 80°F (26°C). It will feature both tropical plants and fauna such as fish, reptiles, birds, and butterflies. This man-made ecosystem will take up over 200,000 square feet of land and is enclosed by a massive dome.
