Description
The carthouse at Wernlas-Deg is a plain structure dating from an unspecified period. It features an old slate roof with slab-coped gable parapets. The long south face of the building is covered with corrugated iron sheeting. On the right gable, there is a recessed boarded door framed with a stopped-chamfered design, accessed by a partly-collapsed stone step. The interior was not inspected during the survey.
