The Project
Off the coast of Talamone, a town on the Maremma Grossetana coast in southern Tuscany, an unconventional sculpture project is taking shape beneath the Mediterranean Sea. Students from an art high school in Grosseto, working alongside local artists and a local fisherman who initiated the project, have been sinking sculptural works onto the seabed — creating what amounts to an underwater art installation that doubles as a marine habitat and a barrier against illegal trawling. The project was reported by NPR in July 2025 and represents a notable intersection of contemporary art, environmental activism, and applied material science in Italy.
The Sculptures and Materials
The submerged works include figures of mermaids, towering giants, and enormous sculptural eyes gazing up from the seafloor. Concrete blocks are sunk alongside the sculptures to create physical barriers that tangle and disable the large nets of trawlers — the fishing method that devastates seafloor ecosystems and depletes fish stocks. The structural mass of the concrete bases anchors the sculptures permanently against strong currents, while the figures above serve as the visual and ecological centrepiece. While concrete is the primary structural material, the sculptural forms — designed for long-term submersion and resistance to marine biofouling — echo the same technical challenges as large-format fiberglass and composite sculptures used in outdoor environments above the waterline: durability, weight management, surface finish, and resistance to salt and biological growth.
Conservation by Design
The project serves multiple ecological functions simultaneously. By blocking trawler access, the submerged sculptures protect Posidonia oceanica seagrass meadows — a critical carbon sink and biodiversity hotspot in the Mediterranean. The structures also provide artificial reef habitat for octopuses, molluscs, and a wide range of invertebrates, effectively becoming a managed marine protected area. The intervention is the latest example of “artivism” — art-driven activism — gaining traction in Italy, where coastal communities are responding to accelerating degradation of marine ecosystems caused by decades of intensive fishing.
What This Means for Large-Scale Sculpture
The Talamone project highlights a growing demand for large-scale sculptural installations in non-traditional environments — underwater, coastal, and ecologically sensitive sites — where material selection is paramount. Projects of this type require structures that can withstand sustained submersion, salt corrosion, and mechanical loading from currents and wave action. For artists, architects, and developers commissioning monumental works, the case of the Talamone sculpture garden underscores that fiberglass and other composite materials — prized for their strength-to-weight ratio, corrosion resistance, and surface versatility — are increasingly well positioned for similar marine and coastal installations.
