Lime Kilns at Bryn Mawr (Aberdo Quarry)

A bank of limekilns standing full-height and facing W, constructed of large blocks of grey stone. The 2nd kiln from the L appears to be the earliest; it is set back slightly and partially ruined. The voussoirs are missing but the stone soffit of the draw-hole tunnel is visible behind a pile of spoil. The shaft of the kiln is partly exposed and has a fire-brick lining. The 2 flanking kilns belong to the next phase, the face of the L kiln built at a slight angle to the rest. Both draw-hole tunnels have round-arched heads of stone voussoirs and stone soffits, with small flues to the rear retaining ironwork and under brick arched heads (partly missing). Domed brickwork above flue of R kiln. To the R of these kilns is a butt joint followed by a further pair of kilns which have wide brick arched heads to the draw-hole tunnels. The soffits are of brick supported on stone side walls. Each tunnel has a stone rear wall containing a flue with cast iron lintel and a pair of cast iron damper doors above.

The high tapering S end wall of the kilns has 2 cast iron tie plates, whilst the N end wall is stepped and partly eroded. On the upper level are fragments of a low rear wall. The tops of 3 shafts can be seen, all lined with brick.
