The present paper explores the presence of the elements that relate back to the sacred Le otto montagne (2016) by Paolo Cognetti and its 2021 film adaptation. Drawing on Gilles Clément's Manifeste du Tiers Paysage, the paper examines how the novel's Third Landscape - spaces left to nature - becomes a site of spiritual reflection. The novel intertwines environmental ethics with a search for the sacred, depicting nature as a space of transcendence for contemporary generations. Throughout the novel, there are elements that evoke a latent spirituality, revealing how the wilderness fosters solitude, redemption, and moral introspection. The present study demonstrates how Le otto montagne reimagines sacrality in a secular age by bridging Clément's ecological thought with theological discourse, engaging with the ethical and spiritual challenges of today's world.
