Llety`r Filiast is a Neolithic burial chamber standing on the slopes of the Great Orme. Its name means The Lair of the Greyhound Bitch and it would have been built before the nearby copper mines were worked by Bronze Age people. The chamber belongs to the portal dolmen group and it is about seven feet long and five feet high. It stands near the remains of a mound which would have covered the chamber.
