“Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar in Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton, Cheddar Man, estimated to be 9,000 years old, was found in 1903. Older remains from the Upper Late Palaeolithic era (12,000–13,000 years ago) have been found. The caves, produced by the activity of an underground river, contain stalactites and stalagmites”. – Wikipedia

Performers in costume perform in the rain during the parade on the second day of the Notting Hill Carnival in west London on August 31, 2015. Nearly one million people are expected by the organizers Sunday and Monday in the streets of west London's Notting Hill to celebrate Caribbean culture at a carnival considered the largest street demonstration in Europe. The Notting Hill Carnival started in the 1960s, when the area had a large population of immigrants recently arrived from the Caribbean and was notorious for its slums – a far cry from today when it is one of London's most expensive places to live.
