Daniel Clarke's ultimate advent calendar counts down to Christmas at St James's Market

Created by illustrator Daniel Clarke, the larger-than-life installation will transform the Pavilion into a stylised cityscape filled with famous London landmarks, where every morning a new door will open to reveal a new festive scene.

To complement this Christmas centrepiece, a digital advent calendar will be launched on St James's London's Instagram where each day throughout December you'll get the chance to win a special prize. Behind every "virtual window" will be an exclusive gift from the area's unique retailers, restaurants, art galleries and hotels.

You can get involved from 1 December until Christmas Eve. Go to www.stjameslondon.co.uk to find out more. Or pop along to the Pavilion to see Daniel's work in action. All images courtesy of Tian Khee Siong.
