Pwll y wrach
Pwll y wrach or Pwll-y-wrach (Welsh for "pool of the witch") is a feature on the River Ennig near Talgarth in south Powys, Wales. The river plunges in two separate streams over a lip of hard rock (the Bishops Frome Limestone, formerly known as the Psammosteus Limestone) into a pool scoured in the softer mudstones of the underlying Raglan Mudstone formation.
The feature occurs within Cwm Pwll-y-wrach, a deep wooded valley that is a Site of Special Scientific Interest and a nature reserve managed by the Brecknock Wildlife Trust.[1] The trust has established trails within the wood to enable public access.
It is suggested that the name derives from the ancient practice of ducking witches in the plunge pool.[2]
