Architecture made out of living trees requires not only using nature as it is but also shaping it to the required form. The first examples of using trees to create living structures are bridges across Asia.
Tree Cathedral Bergamo, Italy

The Chapel Oak Allouville-Bellefosse, France
When the oak tree was nearing 500 years of age, it was struck by lightning. The resulting fire burned slowly through the center and hollowed the tree out. The local Abbot Du Detroit and the village priest, claimed that the lighting striking and hollowing the tree was an event that had happened with holy purpose. So they built a place of pilgrimage devoted to the Virgin Mary in the hollow. In later years, the chapel above was added, as was the staircase.
