On Sunday we drove over to Llangollen, home of the world-famous international eisteddfod, with the intention not of seeing the town itself - pretty though it was - but to find the Pontcysyllte Aqueduct. Built over a ten-year period from 1795, the aqueduct carries the Llangollen canal 127' (39m) above the River Dee.
Designed by Thomas Telford and William Jessop, it was one of the earliest aqueducts to use a cast iron trough, and there are eighteen of these pillars, made of local stone. On one side of the trough is the footpath and railing; on the other thin air. I walked about a quarter of the way across the footpath (don't believe Husband when he says I only did about one tenth; it felt like a quarter) when my stomach contracted and I hastened back from whence I had come rather than carry on and risk a full-scale panic. Husband, of course, 'felt the fear and did it anyway'. Huh!
