The Notting Hill Carnival is an annual event that takes place in the capital city of the UK, London. The event was first held in 1966, making it one of the "newer" such events on this list. The festival takes place on the streets of Notting Hill, which is a part of the Royal Borough of Kensington and Chelsea. It takes place each August, and lasts for two days, meaning you need to keep your timing tight in order to be in London in time for the festival.
The festival is a big and important part of the Black British culture, and in 2006, the festival was voted as one of the icons of England. In the beginning years of the festival, since it didn't have local authority permission, police involvement was aimed at preventing the festival from taking place at all, which caused all kinds of confrontation between the police and the members of the festival.
