Description
MATERIALS: limestone ashlar, possibly of two different types giving a different colour above and below the cornice line.
DESCRIPTION: continuous radius horseshoe arch emphasised by a gigantic roll moulding. This is set in a straight elevation articulated by four bold projecting piers which rise up above the parapet: a slightly battered pair flanking the tunnel mouth, and another pair to terminate the wing walls. Running across this whole elevation is a simple stepped string course or cornice and an equally simple and bold coping. The piers are further emphasized by a second stage to their coping. In the centre of the parapet is a heavily worn plaque panel.
The designation is restricted to the outwardly-visible tunnel mouth and the short stone return inside the mouth; and while the Severn Tunnel itself is of significance as one of the outstanding feats of railway engineering, it is not included in the designation. The west portal is in Wales, and is not designated.
