Neuberg Castle in Hartberg is one of the most important preserved castle of Styria. The medieval hilltop castle was built in the 12th century by Gottschalk Schirling as a border castle against the Hungarian armies. It belonged to the Herberstein family until the late 1900s.
The square tower is the oldest part of the castle, dating from c. 1160. The finely decorated Renaissance ballroom dates from the 16th century. The chapel was consecrated in 1661.
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.
