Italian artist Guiliano Mauri is the father of this spectacular Cattedrale Vegetale (Tree Cathedral), a unique building created out of rows of real living trees. Located at the foot of Mount Arera on the outskirts of Bergamo in Northern Italy, the cathedral is an ever-changing building that will be fully formed over the course of decades – when the trees outgrow their supporting columns and become a piece of natural architecture.

SONEPUR, INDIA - NOVEMBER 15: An elephant is painted in decorative colours during the Sonepur Mela on November 15, 2011 in Sonepur near Patna, India. The cattle fair, held in the Indian state of Bihar, has its origins during ancient times, when people traded elephants and horses across the auspicious river Ganges. The mela used to attract traders from places as distant as Central Asia. It is one of Asia's largest cattle fairs and lasts for a fortnight. (Photo by Daniel Berehulak/Getty Images)
