The Miroir d'eau or Miroir des Quais (Quay Mirror) in Bordeaux is the world's largest reflecting pool, covering 3450m2. Located on the quay of the Garonne in front of the Place de la Bourse, it was built in 2006.
It is made of granite slabs covered by 2 cm of water. In summer, a system allows it to create fog every 15 minutes.
