This book explores interventions that are noteable for their creative and sensitive design, planning or management of the landscape. The featured projects aim to promote interaction between people and the environment by responding to a broad range of human habitats and natural ecosystems in diverse social, cultural and ecolological contexts. In their response to context these projects evolve into Land Art, which is to be understood as a fusion between sculpture, architecture, and landscape architecture. The goal is to draw out the emotions of the spectator who is confronted by these determined, composed enviironments. The structure of this book is inspired by the poet's journey in Dante Alighieri's The Divine Comedy, from which we borrow the narrative structure and symbolic landscape imagery: the circles of Hell, the terraces of Mount Purgatory and the celestial spheres of Heaven.
