Cadw's description

Set within a low rubble field wall alongside the N side of the A5(T), W of the village of Gwalchmai and c.1km WNW of the church of St. Morhiairn.

Following the Act of Union in 1801 a programme to improve the roads between the two capital cities of London and Dublin was initiated. In 1811 Thomas Telford was commissioned to undertake a survey of the roads between London and Holyhead and in 1817 began work on the northern stretch of the road at Shrewsbury. As well as overseeing the work, Thomas Telford also designed every detail of the road, and this milestone is one of a number designed for it. The completion of the stage between Holyhead and Menai Bridge saw all the milestones across Anglesey and into Bangor erected between 1825 and February 1826.

Dressed Anglesey limestone slab, with shallow triangular head and raking chamfered sides. Cast iron inset plate, white lettering on black reading: HOLY- / HEAD / 10 / MONA / 3 / BANGOR / 15.

Listed as a fine example of one of Telford's milestones retaining its cast iron plate.
