Category: Possible.  It is always difficult to establish whether a line of boulders were deliberately placed or are instead the result of glacial or periglacial activity. Generally there must be a presumption in favour of natural origin, but occasionally some detail may hint at the possibility of human intervention. At Careg Lwyd a number of details support the possibility that this line of stones was created by people. The first is the three stone arrangement at the southern end and the second is the fact that the northern stone is prominent on the skyline when viewed from the southern end.  Finally, and most convincingly is the evidence that at least one of the stones has been propped into position with trig stones. Together these details strongly suggest that this site was deliberately fashioned, but whether this happened in prehistoric times is less certain. On balance there is a sound possibility of this feature being a form of prehistoric stone row.


View from the southern end of the boulder alignment. The top stone is visible on the skyline. The three stones at the lower end of the row is somewhat reminiscent of the blocking arrangement at some double rows.

The upper six stones forming the alignment. View from the south.

Looking northward along the boulder alignment.

Stone 6 has been propped with trig stones. This evidence supports the contention that the boulders forming this row were deliberately arranged in a line.

Stones 3 – 6. View from the east (Scale 1m).
