"Tiger's Nest Monastery, Also Known As Paro Taktsang, Is A Sacred Buddhist Site Located In The Cliffside Of The Paro Valley In Bhutan"
"It consists of four temples, interconnected by staircases and bridges, perched on the cliffside over 3,000 meters (10,000 feet) above sea level. The buildings are adorned with intricate carvings and paintings that depict Buddhist teachings and deities."
Considering they still work... why we making stupid ones now? The vertical design is mich safer and more efficient than the pinwheel.
