Caerdroia
A caerdroia is a Welsh turf maze, usually in the sevenfold Cretan labyrinth design. They were created by shepherds on hilltops and were apparently the setting for ritual dances, the nature of which has been lost. At the centre of each caerdroia was a small hillock—in Welsh, twmpath. A gathering for folk dancing in Wales is still called a twmpath dawns. While the caerdroia is typically Welsh, at least one is known to have been constructed abroad. It was discovered by historian Mario Ziccardi in Petrella Tifernina, Italy.
Etymology
Caerdroea or Caer Droea is a Welsh word meaning "a labyrinth, a maze; maze cut by shepherds in the sward, serving as a puzzle." It also means "Troy, Walls-of-Troy". Variations include Caer Droia and Caerdroia, the latter being the spelling generally used today.Because of the similarity between Welsh troeau and the second element Troea, the name was later popularly interpreted as meaning 'fortress of turns'.
Many turf mazes in England were named Troy Town or The Walls of Troy presumably because, in popular legend, the walls of the city of Troy were constructed in such a confusing and complex way that any enemy who entered them would be unable to find his way out.
