Thames Festival is a two-day spectacular, free celebration of London and its river; an exciting mix of arts, spectacle and entertainment, all focused around the River Thames. The Festival commissions new work, and transforms unusual spaces on and around the River Thames with a mixture of street arts, carnival, pyrotechnics, illuminations, art installations, river events, massed choirs, circus and music. The finale is a spectacular illuminated Night Carnival on the streets of the capital, started by London’s Mayor, Ken Livingstone. A vivid mix of masquerade, dance, music, illuminated sculptures and fantastic costumes, the Night Carnival winds along the north and south banks of the Thames. This is followed by a spectacular fireworks display fired from the centre of the river itself.
