Apuolė is a historic village is the oldest Lithuanian settlement mentioned in written sources. Apuolė was an important hill fort of the Curonians, one of the Baltic tribes. Archaeologists dated the wooden fortress to the 1st century AD. The hill fort is situated on the confluence of Luoba and its tributary Brukis rivulet. According to archaeological research, a large village was situated near the hill fort. This would indicate early stages of city development.
Rimbert in his Vita Ansgari described early conflicts between the Curonians and vikings. In 854, Curonians rebelled and refused to pay tribute to Sweden. The rebellious fortress was first attacked by the Danes, who were hoping to make the town pay tribute to Denmark. The locals were victorious and gained much war loot. After learning of Danish failure, King Olof of Sweden organized a large expedition into Curonian lands. Olof first attacked, captured, and burned Grobiņa before besieging Apuolė. According to Rimbert, 15,000 locals defended themselves for eight days but then agreed to surrender: the Curonians paid silver ransom for each man in the fortress, pledged their loyalty to Sweden, and gave 30 hostages to guarantee future payments.
Apuolė was mentioned again only in a 1253 treaty between Bishop of Riga and Livonian Order. The location was described as uncultivated land. The castle was probably destroyed and the villagers moved to safer areas. The settlement was mentioned again in the 17th century. By late 18th century the hill fort attracted attention from historians and archaeologists. The first excavations were carried out by Eduards Volters and Birger Nerman in 1928–1932.
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.
