Llyn Dulyn: The Ghosts of the Black Lake (Nationwide, 1973)

Another Fortean report from Nationwide, the BBC early-evening magazine programme that offered an unrivalled portrait of Britain in the Seventies:

Llyn Dulyn ("Black Lake" in Welsh) lies nestled in the Carneddau range of mountains in Snowdonia. 

A quiet, eerie place, it’s steeped not only in an ancient folklore of evil spirits and witches, but also a more modern variety of ghost story. It was the site of multiple airplane crashes during WWII, and became infamous across North Wales. 

In this clip, the locals speak in hushed tones to reporter John Swinfield of collecting debris from the plane wrecks, catching strange-looking fish and hearing disembodied voices calling out to them.

This report was broadcast on 17 October 1973.
