Ancient labyrinths, known as unicursal, were also referred to as “Cretan” labyrinths, drawing from their roots in Greek mythology. In Great Britain, similar turf mazes based on the same pattern are called ‘caerdroia‘—a Welsh term meaning “City of Troy.” These mazes can still be found in a few remote villages and rural hamlets.
They were typically built around a central core—often shaped like a cross resembling a ‘gammadion’. With the help of the diagrams below, you’ll find it quite straightforward to construct one yourself.
(There are two main historical variations of the Cretan labyrinth, as you can see in Figures. A and B.)
