Ukmergė was first mentioned as a settlement in 1333. It was essentially a wooden fortress that stood on a hill, near the confluence of the Vilkmergė River and the Šventoji River. Ukmergė was attacked by the Teutonic Knights and the Livonian Order in 1333, 1365, 1378, 1386, and even in 1391, already after the Christianization of Lithuania in 1387. During the last attack, Ukmergė was burned to the ground and had to be completely rebuilt.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
