The tunnels under the hills of Gwent

Where does my thing about the Welsh border come from?

In part, of course, it is the children's books of Malcolm Saville. But I also had a holiday in Llanfoist near Abergavenny with one of my mother's many cousins when I was 14.

That and a radio adaptation of Alexander Cordell's Rape of the Fair Country the following year had me hooked.

A combination of natural beauty and industrial archaeology is my ideal landscape, and in this video we explore the the hills around Llanfoist and the tunnels that run beneath them.
