Norske Løve fortress was built from 1852 to 1859 to protect Karljohansvern naval station in Horten in Norway. Its name is a reference to the Coat of Arms of Norway. The fort is still a military area, but is today only used as an administration building for the Norwegian naval officers training school.
The fort was constructed by Balzar Nicolai Garben. It has a moat which can be filled with water and was originally fitted with a circular envelope with 22 open casemates each holding a 3 ton cannon. The fort originally had a complement of 500 men. The open casemates were walled up by the Germans during World War II, but otherwise the fort is largely in its original form.
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.
