Schloss Merten is a building belonging to a former Augustine monastery, which was founded by the neighbouring castle. It is likely that the monastery was donated by Countess Mathilde von Sayn and was first mentioned in a document by Otto von Kappenstein and his wife Kunigunde in 1217.
In 1699 the monastery was burned down. It was not until 1791 that the southern wing was rebuilt. The overall site also includes a small neo-Baroque palace, known as the orangery, which the Counts Droste zu Vischering von Nesselrode-Reichenstein had built around 1909 after acquiring the monastery buildings.
The overall site now houses a home for the elderly and a care home.The grounds with the palace garden and the cafeteria in the orangery are open to the general 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.
