Lyubsha is an archaeological site situated on the right bank of the Volkhov, about 1,500 metres downstream from Staraya Ladoga. As was established by the 1993 excavations, Lyubsha is the site of the earliest Varangian fort in Russia, established in the first half of the 8th century, thus predating Ladoga. Its layout and dimensions closely resemble the contemporaneous hill forts of Great Moravia.
The fortress was destroyed by fire towards the end of the 9th century. Constantine Zuckerman connects its destruction with a conflict (Vadim's uprising) that marked the downfall of the Rus' Khaganate. The Norse name of Lyubsha is unknown.
Immediately north of Lyubsha lies the village of Gorchakovshchina, which used to be a trading post at the head of navigation on the Volkhov, near its ancient entry into Lake Ladoga. Dmitry Machinsky ranks it, along with Ladoga and Alaborg, among the most important centres of the khaganate.
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.
