Why it's Wildland
5.2Three rough conglomerate pillars stand in a field near Trellech. Their name invites a tale of King Harold, but the stones are thought to be thousands of years older than the king.
A short, quiet encounter with a genuinely puzzling prehistoric monument: three puddingstone pillars, cup marks on the largest and stories that grew around them long after their original purpose was lost.

The experience
Allow less than an hour to reach the stones, take in their unusual conglomerate surfaces and consider the competing explanations for their alignment. The site is a brief stop rather than a full-day destination; Trellech’s church and the Virtuous Well offer nearby heritage additions.
Things to do
Compare the three standing stones
Look at their different shapes and sizes. Britain Express describes the row as three large stones in a field and gives approximate heights of 9, 12 and 15 feet.
10–20 minutes
Inspect the largest stone for cup marks
Britain Express reports two cup marks on the south face of the largest stone. Their meaning, and whether the orientation had a purpose, remain uncertain.
5–10 minutes
Unpick the name and its legends
The stones are thought to predate King Harold by millennia. Local stories connect them with Harold, while another tale says Jack o’Kent threw them from a nearby hill; these are legends, not established explanations of the monument.

Verified history
The monument consists of three standing stones made of conglomerate, also called puddingstone. Visit Monmouthshire dates them to about 3,500 years ago and describes the stones as having been brought from nearby and set upright; Britain Express notes that the date is uncertain, with estimates ranging from the middle Neolithic to the early Bronze Age. The stones may have served as markers, seasonal indicators or part of a ceremonial monument, but their purpose is unknown. Britain Express reports two cup marks on the south face of the largest stone and says a likeness of the row was carved on a sundial in St Nicholas’ Church in 1689.
Folklore & legend
Local legend links the stones to King Harold, including stories that they marked a victory or the graves of fallen warriors. The monument is considered much older than King Harold. Another tale credits the giant Jack o’Kent with throwing the stones from a nearby hill. These are local legends, not verified accounts of how the stones were erected.
