A plaque explaining the story behind one of the UK's largest pieces of wall art has been unveiled in Sutton High Street.

The plaque is to accompany the mosaic opposite Waterstone's, which shows images from Sutton's history.

Councillor Graham Tope, executive member for community safety, leisure and libraries, said: “This beautiful mosaic has been a much-loved feature of our high street for the past 17 years, but unless you are a historian the chances are you would not know what all of the intricate panels mean."

The new plaque explains what each section of mosaic means, and the history of the people and places it depicts.

The centre panel shows Henry VIII’s Nonsuch Palace.

Other images show the borough’s heritage buildings - including Honeywood Museum, the old cottage in Cheam, Carshalton Church, Whitehall and The Cock Inn - and past industries, including a Wandle mill, used in the lavender and agricultural trade, and the first iron railway, which ran along the River Wandle.
