If you’re an artist and fancy having your work seen by millions, then this competition is right up your street. Or perhaps that should be ‘across your bridge…’

London Lives is a vibrant, new and free-to-enter art competition developed in partnership by Network Rail, Bankside Gallery and Cass Art, and supported by the Guardian.

The competition aims to explore the concept of London and what it is, celebrating its renowned energy, diversity and originality. From its pulsating streets, bustling transport system, history and colourful markets, through to its serene parks, magnificent river and an evolving cityscape - the judges want to see what London really means to you.

The top 100 entrants will be invited to exhibit their original work at Bankside Gallery and the overall winner will have their work reproduced large scale on Blackfriars Bridge.
