Beaver's Dam, which eventually became known throughout Narnian history with the spelling of Beaversdam, was a historically significant location in the Duchy of Lantern Waste in the northwestern Kingdom of Narnia. Beaver's Dam was originally the home of Mr. and Mrs. Beaver, who aided the Pevensies in fleeing from the Witch's Secret Police. Their abode actually became the first base for the Narnians against Queen Jadis before the unification of Aslan's Army at Aslan's Camp, at the start of the Winter Revolution.
