Sunday TimesWhere Was I? Holiday Competition

Near as I can figure it, through the possibly flawed perceptual filters of my own reality tunnel, the most likely answers this week, seem to me to be:

Q1. Chirk

Q2. Henry Robertson

The initial clues, seem to place us in the county of Wrexham, in the town of Chirk, in Wales, which does appear to have a castle and which according to some of his biographies, is where a footballer called William Henry Meredith (aka Billy Meredith) was born, c 1874. Billy Meredith was a teetotaller, non-smoking, dietician, who eschewed the demon drink and tobacco and instead, chewed on toothpicks and matches. His fans used to send him boxes of toothpicks.

The Llangollen canal passes through Chirk and it and the railway, are carried over the Afon Ceiriog, by an aqueduct and a viaduct, respectively. The aqueduct was built by Thomas Telford and William Jessop and is said in some of the sources I checked,  to be around seventy feet in height. The railway viaduct appears to have been built by an engineer called Henry Robertson (born c 1816), which some references claim is two hundred and eighty three yards long and around one hundred feet high.

Travelling north north west along the aqueduct, would bring us to the Chirk tunnel which seems to be around thirteen hundred and eighty feet long. The canal passes through the shorter Whitehouse tunnel (around five hundred and fifty seven feet in length) before turning west, away from the railway, which continues north, across the Cefn Mawr viaduct (also built by Henry Robertson).

Tracking the canal to the west, would bring us to the point where it turns in a more northerly direction, where it is carried across the Vale of Llangollen and the Afon Dyrfrdwy, by a world heritage site water feature, called the Pontcysyllte Aqueduct, which was also built by Thomas Telford and William Jessop. The lime mortar which holds the stones in the pillars, had ox-blood mixed into it and the sections of the iron trough, which carries the canal water over the aqueduct, are to this day sealed with flannel, lead and liquid sugar. The bridge is said to be one thousand feet long and around one hundred and twenty six feet high with a capacity of around three hundred and thirty thousand gallons.
