Posidonia Festival

An eco-festival in the heart of the Adriatic

The Posidonia Festival was created to showcase and protect one of Italy's most stunning coastal gems: the Tremiti Islands archipelago, located in the municipality of the same name in the Province of Foggia. As the only archipelago in Puglia and the heart of a Marine Protected Area established to safeguard the seabed, Posidonia meadows, and Adriatic biodiversity, it is the perfect setting. Conceived by the Marlin Tremiti team and the Laboratorio del Ma.Re., it is considered the first Italian international eco-festival entirely dedicated to the sea, nature, and sustainable tourism.

Five days of science, sea, and outreach

Each edition turns the islands of San Domino, San Nicola, and Caprara into an open-air laboratory. The program alternates between daytime activities and evening gatherings, all with free admission:

• snorkeling and guided dives led by marine biologists and diving instructors;
• environmental education activities on the beaches and for children;
• boat excursions and citizen science projects open to residents and tourists;
• cleanup of the coves of San Domino and Caprara;
• video screenings and educational sessions at the Laboratorio del Ma.Re.

The evenings, hosted in Piazza Belvedere, serve as the festival's public forum: science communicators, researchers, journalists, and television personalities take the stage to discuss climate, the sea, and conservation, with a special presentation stop on the Gargano coast in Rodi Garganico.

Posidonia oceanica: the star of the show

The event's very name honors Posidonia oceanica, the seagrass that forms vast underwater meadows and acts as a green lung for the Mediterranean: it produces oxygen, protects coasts from erosion, and provides a sanctuary for hundreds of species. The festival's entire message revolves around its protection, bridging scientific research, public awareness, and the promotion of environmentally respectful tourism in the Tremiti Islands.

A project for the maritime heritage of Puglia

Supported over the years by institutions such as the Ministry of Environment and Energy Security, ISPRA, Arpa Puglia, CNR-Irbim, Marevivo, and the Italian Naval League, the Posidonia Festival has become a defining event for the Puglian archipelago and the entire Puglia Region, successfully linking the life of a small island community to the grand challenge of ocean conservation.
