Description

The tunnel entrance to the railway underneath Poundbury Camp dates from 1857. It was constructed after the engineer Isambard Kingdom Brunel was convinced not to create a cutting through the Camp, largely due to the influence of the Reverend William Barnes, the Rector of Winterborne Came, who was a notable Dorset dialect poet and a key figure in establishing the Dorset County Museum. This tunnel is an early example of civil engineering that respects ancient monuments, which is why its entrances are significant. The structure features red brick, a band, a parapet, curved flanking walls, and rusticated ashlar voussoirs.
