Mirów Castle was the residence of the House of Myszkowski. Designed and built in between 1585-1595 by Santi Gucci, by on order of the Bishop of Kraków Piotr Myszkowski. During the first quarter of the 18th century, the castle went into the hands of the Wielkopolski family, and was reconstructed in a Baroque style.
Currently the castle is housing the Wincenty Witos Institution and an Agricultural School. There is a museum in the castle.
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.
