Collier's New Encyclopedia (1921)/Wisby
WISBY, the chief town of the Swedish island of Gotland; is a thriving seaport on the W. coast, and has a fine cathedral (1200). It was once one of the richest of the Hanse towns, with 18 churches, but was taken and destroyed by the Danish King Valdemar III. in 1361, and has never regained its importance. There are great ruins of seven of its former churches; but of the others and of the castle of Wisborg, destroyed by the Danes in 1675, there is little trace left. Pop. about 10,000.
