Welsh hilltop turf mazes (none of which now exist) were called "Caerdroia", which can be translated as "City of Troy" (or perhaps "castle of turns").
An Etruscan terracotta wine-jar from Tragliatella, Italy, shows a seven-ring labyrinth marked with the word TRUIA (which may refer to Troy).
[2] The ancient Roman equestrian event known as the "Troy Game", which involved riding in maze-like patterns, has sometimes been linked to this vase.
Stone-lined labyrinths such as these have proved slightly easier to date than turf mazes (which have to be cleaned out regularly to keep their paths clear, thus destroying any archaeological evidence).
Many of the stone labyrinths around the Baltic coast of Sweden were built by fishermen during rough weather and were believed to entrap evil spirits, the "smågubbar" or "little people" who brought bad luck.
Several similar classical-type labyrinths in Scandinavia have names such as Trojaborg, Trojaburg, Trojborg, Tröborg and Trojienborg, which can all be translated as "City of Troy".
