A TRENCH dug by archaeologists on the Ridgeway has been immortalised as a work of art.

The trench was dug as part of an investigation into life in the area during the Bronze Age.

Artist Simon Callery observed the proceedings, and now his cast of the 60ft long by 6ft deep trench forms the centrepiece of an English Heritage Art Exhibition.

Called Archaeology into Art, it also features photography and painting and is housed at Dover Castle in Kent.

The trench was sunk at St Alfred's Castle near Swindon as archaeologists analysed their finds in a bid to decode the mysteries surrounding life on Britain's oldest walkway some 3,000 years ago.

Mr Callery, 42, said he wanted to create valid artforms based on about seven years of observations of work at the Ridgeway.
