What is "eglwyseg"

The Eglwyseg valley is an area to the north east of Llangollen in Denbighshire, Wales; it is within the boundaries of Llantysilio Community. The name also refers to a widely scattered hamlet in the valley.

Formerly the old township of Eglwysegl or Eglwysegle, the area is now best known for its dramatic rock formations and unspoiled historic landscape.
