The current Węgorzewo town was first mentioned in a 1335 chronicle as Angirburg, or 'eel castle', a settlement of the Teutonic Knights with a block house, a palisade, and a watchtower. The Grand Duke of Lithuania, Kęstutis, destroyed the wooden castle in 1365. Teutonic Knights built new brick castle in 1398. It was situated 2 km away from burnt castle on river island. Near by the castle grew settlement New Village which got allocation privilege in 1514.
From 1525 the castle was a residence of princely district. In 1734 and 1736 King of Poland Stanislaw Leszczynski visited the castle. After World War II the town was burnt by Russian soldiers and the castle was destroyed. It was rebuilt in 1980's.
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.
