Unlike the neighbouring Neurathen Castle very little is known about the history of Altrathen Castle. It was probably built at the same time in the 11th century. The castle was first mentioned in the records in 1289. In 1469 Altrathen and Neurathen castles were slighted.
In 1888 the industrialist, Eduard Seifert, bought the ruins of the castle and rebuilt it in 1893 in a Neogothic style. Of the medieval castle only the cellars and parts of the spiral staircase of the keep have survived.
Aftern 1945 the building acted as a holiday home and later for the East German state bank. In 1995 the site was sold by the Treuhandanstalt to a private owner. Since then the building has been used as a small hotel and restaurant.
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.
