The castle in Severin na Kupi is mentioned for the first time in 1558. The Frankopans erected it above the steep bank of the river Kupa, whilst along with the tower the chronicles also mention a wooden castle from the same period. After the death of the last of the Frankopans and the failure of the Zrinski-Frankopan Conspiracy in 1671 this building was also looted and ruined.
The castle gained its current appearance with a renovation in 1803, during the time of Duke Ivan Oršić. It is a two-storey building of a rectangular ground plan, corners reinforced with cylindrical towers and with an interior courtyard and arcade columns. The Chapel of St Florian, located within the castle complex, has small dimensions with an emphasised arched doorway and turret. Alongside the castle is a garden, which is protected and has been declared as a monument of landscape architecture.
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.
