Caragdûr

The Caragdûr was a steep black precipice of rock located on the north side of the Amon Gwareth (Hill of Watch) near the North Gate of the city of Gondolin.

It was here that Eöl, the Dark Elf was executed for the killing of his wife Aredhel in his attempt to kill his son Maeglin for disobeying him.
