Hazmburk (Hasenburg) is a Gothic castle ruin located on a mountain peak near the town of Libochovice. The castle was home to Zajíc noble family of which Zbyněk Zajíc was the first to own the castle (since 1335). After 1586, it remains desolate and later, in the period of romanticism, it became a source of inspiration for writers, most notably K.H. Mácha. The castle is open to public in summer and can be either accessed from the nearby village of Klapý or from the train stop Slatina pod Hazmburkem.
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.
