Description

Pwll-y-march Limekilns is a double limekiln constructed from squared but uncoursed limestone masonry. It measures approximately 20 meters in overall width and stands about 8 meters high, featuring a straight front wall.

The left kiln includes a low segmental outer arch over the working area, with two kiln working holes that have inner segmental arches. These holes are separated by a thin projecting pier of masonry. Iron lintels are placed over the working holes, with corbelled masonry above, and a re-used flat-bottomed tramrail supports the inner arches.

The right kiln has twin working areas, each featuring a low segmental or slightly pointed outer arch. There is a stonework pier approximately 0.7 meters wide between the two working holes, each of which has a large stone lintel. The top of the structure is not accessible.
