These ferocious fighting female fairies haunt the lonely Welsh lakes and streams, and are known in English as the wives of hell or the wives of the otherworld.

Like feisty freshwater mermaids, these tylwyth teg are not to be messed with, as some have discovered the hard way.

Join author Mark Rees (Ghosts of Wales) as he explores the fascinating history and folklore of the Gwragedd Annwn on the Ghosts and Folklore of Wales podcast... if you dare!

In early 2020, Mark Rees launched the world’s first podcast dedicated to Welsh ghost stories, folklore, myths and legends.

By combining his unique research and insights from many books and articles with long-lost tales from dusty old tomes, this weird and wonderful podcast takes a fascinating look at the country's countless curious subjects.

New episodes are uploaded every Thursday and feature everything from real-life encounters with pesky poltergeists to fantastical beasts from the Mabinogi, to dark and Gothic Halloween/ Nos Calan Gaeaf traditions to the skulled-headed Christmas favourite herself, the Mari Lwyd.
