Churhyard Walls to N and S of St Machreth's Church including Jones and Vaughan Family Monuments

The churchyard walls surrounding St Machreth's Church are low rubble structures that form an irregular semi-circle from the north to the south, dating from the 19th century and earlier. The wall starts at the back of a rubble cottage located just north of the east end of the church. It continues in an arc to connect with the lychgate south of the tower and extends for an additional 40 meters, ending about 12 meters east of the church's east end. This last section acts as a retaining wall, with only a small part of the parapet visible above ground near the lychgate. The large boulder foundations suggest that this part predates the early 19th-century rebuilding of the church. There is an entrance on the northwest with a 20th-century boarded gate; from this point to the lychgate, the wall slopes down and is topped with slate slabs.

The churchyard remains largely unchanged and features numerous 18th and 19th-century gravestones and chest tombs arranged in their original haphazard layout. Among these, notable features include the mid-19th-century enclosure for the Jones family of Hengwrt to the west, which is surrounded by Gothic cast iron railings, and a large raised slate sarcophagus for Sir Robert Williames Vaughan and his family to the northwest, dating from 1843 to 1858.
