I must owe Wikipedia a few bob today, but I think this is right.
Loggerheads is a village in Denbighshire, Wales on the River Alyn, a tributary of the River Dee.
It has a country park which follows the course of the River Alyn through karstic limestone countryside including the sites of old lead mines and mills. there is a working flour mill on site.
A leat or leete, built around 1824 follows the side of the valley nearby and was used to carry water to the lead mines of Mold Mines, on land owned by the Grosvenor family. It is now the popular Leete Walk. The name Loggerheads may come from the dispute over estate boundaries between the lordships of Mold and Llanferres.
