Giuliano Mauri has launched an unusual "live" architectural design. The essence of the project lies in the fact that inside the wicker 42 columns, seedlings were planted hornbeam (small genus of deciduous trees of the birch family). As planned by Giuliano, after fifteen years of limiting frames, columns will be too tight for trees and destroyed. Hornbeams themselves form a natural structure of the present Cathedral of the living tree. Unfortunately, Giuliano Mauri did not live up to the present day.
Work on the project finished by his son, Roberto Mauri. The building is located on the outskirts of the Italian city of Bergamo in Northern Italy. The project covers an area of 650 sq.m. Needed for the construction of 80 hornbeam plants, 600 bars of chestnut and spruce trunks in 1800. For the connection of elements used is about 6 kilometers nut vine.
