It has been almost thirty years since Filippo Dobrilla started to sculpt a giant male nude inside a cave 650 metres deep in the Apuan Alps. This almost inaccessible place has jealously protected his secret: his youthful passion for a fellow climber, a passion Filippo was only able to indulge in here in the intimacy of this cave. Even after it was over and ever since then, Filippo has been returning regularly to the cave to work on the most important sculpture of his life, a masterpiece no one will see.
