Walls, Piers And Bridge About 40 Metres West Of Entrance To Churchyard Of Church Of St Mary

The structure consists of walls, piers, and a bridge located about 40 metres west of the entrance to the churchyard of the Church of St. Mary. It was built in the early 19th century and features brick walls with stone dressings, including volcanic stone at the tunnel entry and part of the tunnel. The walls extend approximately 50 metres, sloping at each end, with a height of about 2 metres on the north side and 1 metre on the south side. They include a stone plinth and coping, with brick piers positioned about 8 metres apart.

At the western end, there are a pair of square stone piers with rectangular recesses on the sides and hipped tops. Similar pairs of piers are found at both the western and eastern approaches to the bridge. On top of the bridge, there is another pair of stone piers featuring a cornice and hipped tops. The northern tunnel entry, made of volcanic stone, has a wide arch with a large keystone and five inner arches to the vault, each with a pendant keystone springing from pilasters. A continuous cornice runs along the top, and the first bay of the tunnel vault is faced in variegated coloured volcanic stones—yellow, black, and grey—while the other bays are faced in brick.

The southern tunnel entry has some volcanic stone missing, exposing the brick core. It features a similar arch and an inner curtain wall that is set back, with a smaller segmental-headed entry and a heavy keystone, along with small triangular openings on each side. This structure is part of the ornamental walk around Dodington Park and has the appearance of a grotto. At the time of the survey in September 1984, it was noted to be in poor condition.
