There are two sites scheduled under this number: a) quarry barracks (called the Anglesey Barracks) and b) an incline of the 'A' series with double-track self-acting planes and three brake-drum houses.

a. The barracks consist of two rows of twelve units, the rows c. 20 ft apart and facing one another. Each unit measures about 20 ft x 10 ft and is divided into two rooms. The larger room, c. 11 ft across, contains a fireplace and a doorway leading into the smaller room. All the roofing slates and timbers have been removed, and a variety of scrub trees is growing both inside and outside the barracks.

b. The incline is in three parts, each part with a brake-drum house at the upper end. All is in reasonable condition, having been restored by Gwynedd County Council. The uppermost of the brake-drum houses has a number of holes in its roof.

The monument is of national importance for its potential to enhance our knowledge of the slate 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.

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