In which London neighborhood is Europe's largest Carnival held? The answer is Notting Hill.

The Notting Hill Carnival is a major Caribbean festival held annually in west London, centered on Notting Hill and the Ladbroke Grove area. It began in 1966 and grew from events organized by members of London's Caribbean communities, especially people with roots in Trinidad and other West Indian islands.

The celebration combines elaborate masquerade costumes, steelpan music, sound systems, dancing and Caribbean food. Its main public events take place over the August bank-holiday weekend, with a large procession moving through surrounding streets. Attendance is commonly estimated at about two million people, making it one of the world's largest street festivals.

A common mix-up is confusing the carnival with the wider borough or nearby districts. Notting Hill is the neighborhood named in the festival's official title; Kensington and Ladbroke Grove are useful geographic references, but they are not the quiz's canonical answer.
