Troy Town

Many turf mazes in England were named Troy Town, Troy-town or variations on that theme 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. Welsh hilltop turf mazes were called "Caerdroia", which can be translated as "City of Troy".

W. H. Matthews, in his Mazes and Labyrinths, gives the name as "Troy-town". More recent writers prefer "Troy Town".
