Part of Kilgetty Colliery (nprn 308436). The chimney probably dates from the early to mid nineteenth century. The height appears to have been about 20m but the upper part was demolished by the Army in 1972. It appears to have been built as a boilerhouse chimney, but may later have served for mine ventilation: such ventilation chimneys are a rarity. The stump of the chimney is about 2.5 m square externally and 1.25 m square internally, and rises to a surviving height of about 4.5 m above the ground level of the yard. It is built of rubble sandstone with dressed quoins in a style similar to that of the weighbridge office (nprn 33588). The chimney tapers slightly to a height of about 3 m, above which its taper is more gentle.
