Description

The remains of a group of cement kiln structures forming part of the former West Medina Cement Mills, constructed in the late 19th century in multiple phases. The complex comprises the ruins of bottle kilns, a pair of kilns with heated raised drying floors, and a chamber kiln. The structures are built from various types of concrete and cement with brick facing and reinforcement; the surviving kiln pots are principally rendered brick.

The kiln complex is arranged in an L-shaped plan. At the north end stands the east-west kiln structure, measuring approximately 44 metres long and 18 metres wide, constructed from concrete made with broken brick fragments and small rounded beach or river shingle as aggregate, reinforced by reused rail track. Two kiln pots at the east end, surrounded by the remains of an upper wall with arch openings, have been infilled with waste material. The outer face of the east side features further arched openings, likely relating to kiln unloading. Extending westward are a parallel pair of drying chambers divided by a concrete wall, built in two phases. The drying floors consist of iron plates and concrete slabs sitting on brick and concrete walls; these have suffered partial collapse, particularly along the north chamber. At the west end of the north drying chamber floor is a hole interpreted as the possible remains of an additional chimney. Below the floors lie brick-wall voids used for the movement of hot gases. The void network under the south platform is more complex, incorporating upper and lower voids to allow hot gas to pass under the floor at least twice. The structure stands on six concrete and brick tunnels, with the most easterly providing access to the arched unloading openings at the base of the kiln pots. At the west end are three arched buttresses added at a later stage; a metal plaque reading 'CF&S 1875' has been found in association with one buttress. A brick chimney stack at the west end has been truncated. It is likely there were originally an upper drying floor with suspended plates and an open-sided superstructure with a roof over the drying floor; these are no longer extant.

To the south are the remains of a row of bottle kilns, originally consisting of six brick-built examples. The two most easterly kiln pots were incorporated into the north-south chamber kiln. The four westerly bottle kilns have suffered the greatest loss of fabric, including loss of the upper tapering chimneys. The surviving kiln pot remains have been infilled with waste material. At least three of the bottle kilns retain their south-facing brick-arch unloading openings, partially buried. The kilns are constructed of mortared brick and concrete with rounded beach or river shingle aggregate. Joist holes in the south face of the kiln bank are evidence of a former wooden loading platform. Iron rail tracks have been uncovered at the base of the kilns for unloading and moving material.

The north-south chamber kiln measures approximately 26 metres long and 17 metres wide. At the north end are the remains of a pair of kiln pots, infilled with waste, formerly part of the bottle kiln bank. A concreted stairway on the east side provides access to the tops of the kiln pots. The drying floor extends to the south, constructed of bricks and concrete slabs covered in cement. The chamber platform is divided down the middle by a low north-south wall to form two drying floors. Below is a brick void with an arched roof running under the drying floor. The brick chimney stack at the south end has been truncated. The chamber platform sits on three arched tunnels; the north tunnel incorporates the brick-arch unloading openings at the base of the kiln pots, the central tunnel has been blocked on the east side and may have been used for storage. It is likely there would have also been a superstructure over the drying floor; this is no longer extant.

The kiln complex is partially earth-covered and ruinous.
