Cadw's description

The milestone stands in the road verge, near Melin Pantperthog.

A series of milestones were erected along the Machynlleth to Dolgellau turnpike in the early C19 to mark the distances, as required by charter.

The milestone consists of a simple slate slab, whitewashed, with its upper corners cut back at an angle to form a 3 equal-sided top. Incised on the front the inscription Mach / 3 M. Below, a bench mark.

Included as one of the better preserved milestones along this section of the road, and one still serving its original purpose.
