Artist Giuliano Mauri began the towering project in 2001, creating 42 columns that arc towards each other to form a leafy basilica and five grand aisles. Located near the foot of northern Italy’s Mount Arera is made up entirely of trees. The framework columns will eventually rot away and decay, to be replaced by the hornbeam trees planted in the center of each frame. As these grow, their canopies will mesh together to form the vaulted ceiling of a Gothic cathedral.
This stunning example of blend of nature and spirituality .
