Description
Gelli is a square walled enclosure located at the corner of a field boundary. Inside the enclosure, there are two buildings constructed from rubble masonry, both featuring hipped slate roofs. One building stands freely in the eastern corner of the enclosure, while the other, identified on the Ordnance Survey map as a "limekiln," is built into the western corner. A clearly visible entrance in the southeast wall leads out to a disused limestone quarry. The interior was not inspected during the survey.
