The milestone was erected as part of the improvements to the London to Holyhead Road undertaken by Thomas Telford, engineer, from 1819 to improve communications between London and Dublin. The poor state of the road to Ireland exercised Parliament from before 1810, and a survey was carried out by Telford in 1811. Monies granted following the setting up of a commission in 1815, but work on this section could not take place until the amalgamation of the seven existing turnpike trusts, authorised in 1819. The road was not completed until the opening of the Menai Bridge, and the construction of the 20 mile (32km) Anglesey section in 1828. Telford designed the road formation, and details of ancillary structures, including the tollhouses and milestones.  

A tapered limestone pillar, approximately 1.4m high with a gabled top, the front and sides point dressed, and the front face recessed and set with a cast iron plate reading HOLY-/ HEAD / 61 / CERNIOGE / 7M-2F / CORWEN / 5M-6F.  

 

Included as one of the important series of milestones erected under Thomas Telford as part of one of the first modern style major road improvement schemes of national importance. This being one of very few Welsh examples now surviving east of Betws-y-coed. Group value with the listed section of Holyhead Road and Pont Glyn-dyffwys.
