Once again I meet up with archaeologist Tomos Jones at an excavation, this time at Caerfai just outside St David's. The excavation was being run by DigVentures, a project that brings the archaeological experience to all. You can find out more on their website: digventures.com.

Tomos is a native Welsh speaker and you'll hear that I'm not but I do ask him some questions in Welsh anyway, even though most of our conversation is in English.
