The Mayor's Thames Festival '11 September 10, 2011

Launched in 1997, The Mayor's Thames Festival has grown to become London's largest free open-air arts festival.

Events
Saturday, 10th and Sunday, 11th September, are the dates set aside for the festival which is open from noon until 10pm between Westminster Bridge and Tower Bridge. Many Thames Festival activities are based on public participation. The festival commissions new work, and transforms unusual spaces on and around the River Thames with a mixture of street arts, performance, carnival, pyrotechnics, illuminations, art installations, exhibitions, river events, massed choirs, circus, music and dance, food and feasting. The finale is a magical illuminated Night Procession that winds along the north and south banks of the Thames, followed by a fireworks display fired from the centre of the river itself.
