Some more from Dyffryn Ceiriog:
Derwen hynafol (ancient oak) with a striking name: The Great Oak of Gate of the Dead ("Thought to date back to the reign of King Egbert in 802"
). The reputed site of the Battle of Crogen
(sorry about cutting off the part Cymraeg - the sun was in my eyes and I couldn't see the screen on the camera - good reason for getting a camera with a proper viewfinder next time!)
... and now for something completely different:
On a south-facing slope in DC, eirlysiau aroglus (fragrant snowdrops - hopefully 'aroglus' means what I think it means and not simply 'smelly'!)
