Notting Hill Carnival is a street carnival in the Notting Hill district of London. The carnival has been in existence since 1966 and takes place on the l;ast weekend in August. it was the inspiration jf black immigrants from the Caribbean, particularly from Trinidad, where a great pre-Lenten carnival has been held for many decades. From  simple bewginnings, it has developed into a huge multicultural arts festival attended by up to two  million people. Following the tradition of the Trinidadian carnival, great emphasis is placed on fantastic costume displays and steel drum music. Calypso songs and soca (a mixture of soul and calypso) are also essential  elements in the festivities. In addition to the lively procession af costume, soca, and steel bands which winds its way over a route of some 7,5 km of the area, the festival also plays host to other musicains playing reggae and hip-hop, as well as hundreds of the street stalls selling exotic foods and crafts from all perts of world.
