Many American cities have been destroyed via a great conflagration, and the Great Chicago Fire of 1871 is certainly one of the best known. The Chicago History Museum has created this two-part website which explores the history of the fire and also the ways in which the fire has been remembered. In the first section ("The Great Chicago Fire") visitors can look over essays about pre-fire Chicago from writers like Frederick Francis Cook and Bessie Bradwell Helmer, who were present at the fire. Back on the homepage, the "Special Features" area includes a chronological timeline of the fire, an interactive tour of fire landmarks, and some 3D views. The second primary section of the site is titled "The Web Of Memory" and it contains eyewitness reports, front page reporting from the frontlines, and a clutch of documents about the legend of Mrs. O'Leary's cow.
