Gyllebohus was a medieval Danish castle. The earliest known owner was Verner Brahe in 1280. The stone castle was built between 1538-1544 Laurids Lauridsen Knob and was one of the largest castles in Scania. It was burned down several times in wars, the latest destruction happened in 1700. Today some fragments remain of Gyllebohus. The adjacent manor house was built Hedwig Sofia Schönström in 1813-1818 and it is privately owned.
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.
