In the late 18th century, Richard Pennant, 1st Baron Penrhyn, built a road from Bangor through the Nant Ffrancon and Dyffryn Ogwen to Betws-y-Coed, and eventually through to Shrewsbury (in use by 1798). In 1801, Lord Penrhyn built the then named Capel Curig Inn. In 1808 the Mail coach which ran from Holyhead to Shrewsbury began running via Capel Curig. The Mail coach ceased operation in 1848 following the opening of the Chester and Holyhead Railway. The inn wasn't built on the road (now the A5), but some distance from it on the present site to facilitate enjoyment of the superb view of Llynnau Mymbyr (the lakes) and the Snowdon horseshoe.
