Row of kilns at former Afon Wen Portland Cement Works

This is a row of 10 former kilns located at the former Afon Wen Portland Cement Works, built into a steep bank. At the lower level, there is a battered wall featuring segmental-headed draw arches of varying heights, along with an impost band, except for the three right-hand kilns which are possibly later additions. The second arch from the left has been repaired. The kilns themselves are segmental-vaulted and have been infilled at the front, but they still include round-headed openings. The kilns at both the northern and southern ends have mostly collapsed, while the remaining kilns are in varying conditions. At the left (northern) end, there are brick steps leading to the upper level. Inside the draw arches, there are narrow pits where the cement was drawn, and above these, the structure widens out into the main chamber of the kilns, which feature battered back walls.
