Launched in 1997 with an amazing high wire walk across the Thames, the Mayor's Thames Festival has grown to become the capital's largest free, open-air arts festival that now attracts close to 500,000 people each year. The festival showcases high-profile, cutting-edge arts events on and around the river, and also offers the best in street arts, with pyrotechnics, illuminations, art installations, river events, street theatre, massed choirs, circus and music. Tens of thousands dance in the streets at the festival's climactic event, a spectacular Night Carnival that is a vivid mixture of masquerade, dance, music and fantastic costumes.
