The Tiger‘s Nest, Bhutan

One of the world’s most precariously placed monasteries, Paro Taktsang (better known as the Tiger’s Nest) perches tentatively on a cliffside in the upper Paro valley in Bhutan. The elegant structure is built around a cave in the cliff face that is said to have been used by Guru Padmasambhava for meditation in the 8th century. Legend has it that he flew to the cave on the back of a female tiger.
