Close to the ancient town of Wareham in the English county of Dorset is a visitor attraction that is not quite like any other. Only a short distance on the main A351 between Wareham and Corfe Castle, it is wholly English, but at times it could be Canadian, at others Norwegian. It is a chamelion place, for more than one reason, and it's called the Blue Pool.

The Blue Pool at Furzebrook was once a claypit, which accounts for a rare phenomenon that has attracted visitors from across the world ever since it opened to the public in 1935. It retains miniscule, light diffracting particles of clay in the water, causing a spectrum of colour variations, sometimes from minute to minute. Now deep turquoise, now emerald green, the Pool is a constantly changing delight to the eye.
