This site is a splendid example of a rural brickworks in a spectacular coastal setting. Little or nothing is published so information about the history of the site will have to be obtained from primary sources.

Even so the monument is clearly of considerable importance as it is possible to see the complete process of brick manufacture indicated by the remains on the ground.

The quarry. Clearly visible to the W and S.

The incline. For transporting raw material to brickworks. This can still clearly be seen although it is somewhat ruined in places. The winding house at the top also survives, with part of the winding drum and brake mechanism still in place (although damaged).

The stone breaker and preparation structures. The heavy cast iron stone breaker (bearing manufacturer's details) is in situ, although parts have been removed. Buildings associated are unroofed and some of the walls appear a little precarious. These have been built in a series of 'terraces' against the steep slope. The lower buildings seem to have accommodated a boiler or engine, and one tall chimney stack survives, although its condition gives cause for concern. Other buildings, perhaps where bricks were formed, are rather more ruined.

Kilns. Three well-preserved, dome-shaped kilns survive.

Other buildings. To the NW of the kilns are the foundations and W gables of a range of buildings of uncertain function - perhaps where bricks were formed. At the northernmost end of the complex is a large and impressive building of two storeys, with part of an engine at the SW corner.

Quay. To seaward are the remains of a somewhat damaged quay where fired bricks were loaded for transport by sea.

The whole process from extraction of raw material to the export of the finished product is represented and can be seen.

The monument is of national importance for its potential to enhance our knowledge of post medieval industry. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
