Upsal a town of Sweden, forty-five miles northwest of Stockholm, was, during the Middle Ages, the stronghold of paganism. It has a beautiful Gothic cathedral, built from 1258 to 1435. Its interior is magnificent and richly decorated, but its exterior has suffered much from fire, notably in the conflagration of 1702. It is the finest cathedral in that region.
