Caerdroia is the Welsh word for Troy (‘Troea’), which by a linguistic parallel – ‘troeau’ translates as ‘bends’ – was known as the ‘Castle of Turns’, so-called for its mythically unnavigable system of walls and streets. Historically, Welsh shepherds are said to have created their own ‘caerdroia’, sevenfold mazes that were associated with sacred dances and ceremonial feasts. Tilson’s maze mimics these medieval turf versions, whose paths were delineated by raised earth rather than surrounded on either side by walls.
