Summary :
Moel Trigarn is a hillfort occupying the summit of a craggy, conical hill that rises to 360m above sea level. The main defensive circuit comprises two, widely-spaced, vegetation-covered, dilapidated stone-built banks with flanking ditches. On the south side the defensive circuit takes in a low cliff - there is no built defence here. On the other three sides the banks curve around the hilltop forming an oval inner enclosure c. 180m east-west and 120m north-south. The gap between the two banks is approximately 45m. The inner bank rises about 1m above the interior and 3m-4m above the ditch. It has largely collapsed into the ditch, obscuring much of it. The outer bank is slighter. Dry-stone walling facing is visible on the inner and outer face of the outer bank and in sheep scraps on the outer face of the inner bank. The outer bank runs up to meet the inner bank on the west side - here there is a simple entrance through the inner bank. There is also a simple entrance through the inner bank on the east side leading into space between the ramparts. A sub-rectangular annexe, 145m by 75m, is attached to the northeast side of the outer bank and is defined by vegetation-covered stony bank. The interior is domed, with the summit crowned by three massive cairns (hence the name) considered to be Bronze Age funerary monuments. Right across the hilltop, within the inner enclosure, the space between the ramparts and in the annexe, are numerous (perhaps over 200) circular platforms, probably house sites. Limited excavation by Baring Gould in 1900 revealed artefacts consistent with late prehistoric/Romano-British occupation.

The RCAHMW has undertaken a detailed survey of the site.

The site is under heather. It is frequently visited, but seems to be suffering little from visitor erosion. There is some damage the ramparts from sheep-scraps, particularly the inner one.

Moel Trigarn is a hillfort occupying the summit of a craggy, conical hill that rises to 360m above sea level. The main defensive circuit comprises two, widely-spaced, vegetation-covered, dilapidated stone-built banks with flanking ditches. On the south side the defensive circuit takes in a low cliff - there is no built defence here. On the other three sides the banks curve around the hilltop forming an oval inner enclosure c. 180m E-W and 120m N-S. The gap between the two banks is approximately 45m. The inner bank rises about 1m above the interior and 3m-4m above the ditch. It has largely collapsed into the ditch, obscuring much of it. The outer bank is slighter. Dry-stone walling facing is visible on the inner and outer face of the outer bank and in sheep scraps on the outer face of the inner bank. The outer bank runs up to meet the inner bank on the west side - here there is a simple entrance through the inner bank. There is also a simple entrance through the inner bank on the east side leading into space between the ramparts. A sub-rectangular annexe, 145m by 75m, is attached to the NE side of the outer bank and is defined by vegetation-covered stony bank. The interior is domed, with the summit crowned by three massive cairns (hence the name) considered to be Bronze Age funerary monuments. Right across the hilltop, within the inner enclosure, the space between the ramparts and in the annexe, are numerous (perhaps over 200) circular platforms, probably house sites.
