Row of kilns at former Afon Wen Portland Cement Works

A bank of 10 former kilns built into a steep bank. At the lower level is a battered wall with segmental-headed draw arches of varying heights, and impost band (except to the 3 R-hand kilns which are possibly later), above which are joist holes and tie plate. The arch second from the L is repaired. The kilns themselves are segmental-vaulted and are infilled to the front but incorporate round-headed openings. The kilns at the N and S ends have mostly collapsed while the remainder are in varying conditions. At the L (N) end are brick steps to the upper level. The interior of the draw arches have narrow pits where the cement was drawn, and above them the structure widens out to the main chamber of the kilns which have battered back walls.
