The exhibition Costantino Brundu: paths of a naturalist is dedicated to Costantino Brundu, a scholar from Tempio linked by a deep passion to his land. For many years a teacher of Literature at the Technical Institute of Tempio, Costantino Brundu was a great connoisseur of the territory, a convinced environmentalist, and an active interlocutor with the institutions responsible for environmental protection. A versatile artist, a free man, courageous in defending the territory, he carried on with conviction and firmness many battles for the defense of Sardinia's environmental heritage. The places represented in the exhibition dedicated to him by the Organic Museum focus on Monte Limbara, the granite giant of Gallura, one of the most suggestive natural and human landscapes of the island. The exhibited images, along with excerpts from unpublished texts of a guide he wrote but never published, tell a corner of Sardinia where nature fascinates precisely because of its inexhaustible ability to surprise with the rugged and wild forms of the rocks, the explosions of lights and colors, the gushing of crystal-clear spring waters. The exhibition, curated by journalist Giovanni Gelsomino, was realized with the precious support of the Brundu family.
