Denbigh's medieval walls are among the best-preserved and most complete in the country (perhaps the best example of Edwardian town walls outside of Conwy). The walls encircle the old 'town ward' created as part of Edward I's plan for a new English-dominated borough at Denbigh. Denbigh, Clwyd, Wales
The tower and a short section of wall are all that remains of a medieval chapel of ease dedicated to St Hilary, built into the late 13th-century town walls of Denbigh. The chapel was created sometime around 1300 as a dependency of Whitchurch just over a mile to the east. Castle Hill, Denbigh, Clwyd, Wales, LL16 3NA
Eliseg's Pillar is a 9th-century stone cross erected by Cyngen, the last king of Powys, in memory of his great-grandfather, King Eliseg. The pillar now stands to a height of just over six feet, but it was originally at least twice that height, and had a large cross on top. A542, Pentrefelin, Clwyd, Wales
The Maen Achwyfan Cross is a beautifully carved 10th-century wheel cross. The cross shows strong Scandinavian influence in the carving style, similar to crosses in Northumbria of the same age. It stands about 3.43 metres high (roughly 11 1/4 feet for those, like me, who think in old units of measurement!). Whitford, Clwyd, Wales
One of the major engineering triumphs of Thomas Telford's remarkable career, the Pontcysyllte Aqueduct carries the Shropshire Union Canal across the River Dee. The aqueduct is 127 feet above the valley floor (about 39 metres). It was one of the very first aqueducts to make use of a cast-iron trough. Although Telford usually gets most of the credit for Pontcysyllte, it was actually a joint effort with William Jessop. B5434, Station Road, Trevor, Trevor Basin, Clwyd, Wales, LL20 7TG
