This is a well preserved semicircular kiln, about 8 m in height. It is constructed from rubble limestone brought to courses, with small offsets at intervals to achieve a slight batter. There are numerous beam or putlog holes in the face of the masonry. The kiln stands against high ground with revetment wings each side. There are opposed working apertures each with corbelling and an arch at the front.

It is the remains of one of six limekilns, probably mid-C19, in an extensive area of quarrying. The three kilns to the South of the road are in Kiln Park (whilst the three to the North of the road are in Croft Quarries). Quarrying at both sites is indicated (graphically or by field-name) on Picton estate plans of c.1850, and all six kilns are marked as 'old limekilns' on the 1887 Ordnance Survey plan.
