Camelot

Camelot is a castle and court associated with the legendary King Arthur. Absent in the early Arthurian material, Camelot first appeared in 12th-century French romances and eventually came to be described as the fantastic capital of Arthur's realm and a symbol of the Arthurian world. The stories locate it somewhere in Great Britain and sometimes associate it with real cities, though more usually its precise location is not revealed. Most scholars regard it as being entirely fictional, its geography being perfect for romance writers; Arthurian scholar Norris J. Lacy commented that "Camelot, located no where in particular, can be anywhere". Nevertheless arguments about the location of the "real Camelot" have occurred since the 15th century and continue to rage today in popular works and for tourism purposes.

Although several Autobots and Decepticons journeyed back to this time period, they did not visit Camelot.

Perhaps they thought it was a silly place.
