The Milwr Tunnel is a mine drainage adit running some 10 miles from the hamlet of Cadole near Loggerheads, Denbighshire to Bagillt on the Dee Estuary in North Wales. It was originally built to drain the lead mines beneath Halkyn Mountain, which were plagued with flooding in their lower levels, but enabled the exploitation of new lodes and was variously used for the extraction of lead, zinc and limestone during its working history. It is part of a network of mines, lodes and natural cave systems - the Halkyn United Mines - that extends for up to 100 kilometres, the longest in the United Kingdom.
It forms part of the mine drainage system that is responsible for draining Ogof Hesp Alyn and leaving much of the River Alyn between Loggerheads and Rhydymwyn dry during summer months.

Famous quotes containing the word tunnel:
“It is the light
At the end of the tunnel as it might be seen
By him looking out somberly at the shower,
The picture of hope a dying man might turn away from,
Realizing that hope is something else, something concrete
You can’t have.”
—John Ashbery (b. 1927)
