Just offshore from Noli, a cluster of transparent plastic biospheres sits on the seabed, housing what is arguably the world's most unusual farm. Nemo's Garden is an experiment in underwater agriculture, where tomatoes, basil, strawberries, lettuce, and other crops grow inside air-filled domes submerged 6 to 10 metres below the surface. The stable temperature, controlled humidity, and CO2 enrichment inside the biospheres have produced surprisingly vigorous plants.
The garden was created by the Ocean Reef Group and has become both a scientific project and a tourist attraction. Glass-bottom boat tours from Noli's beach provide a view of the domes from above, and during the summer season the organisers sometimes offer guided snorkelling or diving visits to look inside. It is a genuinely strange sight — a cluster of alien modules on the Ligurian seafloor, with green plants clearly visible inside — and one you will not find anywhere else in the world. Check the Nemo's Garden website for visiting information before you arrive.
