has no connection with the Homeric “Troy,” but means a maze, labyrinth, or bower. (Welsh troi, to turn; troedle, a trodden place [? street], whence the archaic trode, a path or track; Anglo-Saxon thraw-an, to twist or turn.) There are numerous Troys and Troy-towns in Great Britain and North America. The upper garden of Kensington Palace was called “the siege of Troy.”
A Troy-town is about equivalent to “Julian's Bower,” mentioned in Halliwell's Archaic Dictionary.
