The original Gothic castle of Grabštejn (or Grafenstein) was founded in the 13th century. In 1562, it was bought by Crown Chancellor Georg Mehl von Strelitz. Between 1566 and 1586, he had rebuilt the castle in Renaissance style and thus turned it into a representative chateau.
Georg Mehl also had a steward's house built below the castle, which was around the year 1830 rebuilt in Classicist style. Shortly before that – around 1818 – Christian of Clam-Gallas had built the New Castle near the Old Castle. The new building was surrounded by a large garden with a number of valuable plants. The Old Castle has preserved its original Renaissance appearance despite a fire which damaged its upper floors in 1843.
The House of Clam-Gallas owned Grabštejn since 1704 until it was confiscated in 1945. After the Second World War, the castle was open to the public, but in 1953, the whole castle complex was taken over by the Ministry of Defence. The Old Castle's condition significantly deteriorated after the army left in the late 1980s.
Repairs and restorations began in 1989. Nowadays, Grabštejn is one of the best restored monuments of great importance in the Czech Republic. The castle was opened to the public again in 1993. The tower offers a marvellous view of the three-border-triangle, the castle's northern wing, and the vault. The most touristically attractive part of the castle interior is the St. Barbara chapel decorated with Renaissance fresco paintings from the 16th century. All parts of the ceiling and walls are ornamented in with interlaced figural, animal, and heraldic motifs.
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.
