This is the English translation of Tre'r Ceiri - one of the best Iron Age Hillforts in Europe. But actually, the word for giants is "cewri" nor "ceiri". The word "ceiri" is the plural of the word "caer", as in Caernarfon which means fort. So Tre'r Ceiri actually means Town of the Castles, which doesn't have quite the same legendary ring.

|The correct hill is the smaller one to the south east.|
