Frymburk (Friedenburg) castle was founded in the beginning of the 14th century probably by the Lords of Lipá. The castle is surrounded by the River Olešenka and lies next to Nový Hrádek. It has a big round tower, partly collapsed. A water basin is carved in the rock in a small courtyard.
The castle is for the first time mentioned in the year 1354, when it was allegedly in property of not closely known Matyáš of Frymburk. The castle as well as surrounding manors at Nový Hrádek were taken over by Hynek of Dubá and in Náchod (in 1368), but there also appears name of Jinřich of Lipá and Jan of Lichtenberk. In the beginning of the 15th century the manor belonged to Dobruška.
In the course of the Thirty Year’s War the castle was conquered by peasant rebels and some time later it was burnt by Swedish together with Nový Hrádek. It has never been renewed. The ruins are today unstable and dangerous, and therefore not available for public.
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.
