Sielecki Castle is located on the left bank of the Czarna Przemsza River. Originally a defensive fortification, the castle expanded in 1620 into a four-wing complex with corner towers, perhaps using earlier buildings. The castle was built of broken limestone and brick. Storey building with basement. After the fire in 1824, the castle was rebuilt in 1832, but the east wing with the entrance gate was demolished and the moats were filled. Despite these changes, the original defensive character is evidenced by the shape of the block, four corner towers and projections on the extension of the side wings. It is currently a three-winged building with an open courtyard.
In 1994 the city of Sosnowiec took over the destroyed castle. Currently, the castle houses the Sosnowiec Art Center. This local government institution co-creates the cultural life of the city by organizing exhibitions, concerts and various culture-forming meetings.
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.
