Bleijenbeek Castle was built of bricks around 1300. According to the 19th-century historian A.J. van der Aa, the castle is known for its numerous sieges by the armies of Guelders and Spain. In 1580, the castle was besieged by the forces of Guelders, but it was defended bravely by the lord of the castle, Marten Schenk. When the Duke of Parma sent cavalry, the besieging army had to retreat. In 1589, Schenk changed sides, and the castle was besieged by Marcus van Rije, the stadtholder of Guelders appointed by the Spanish king; this time, the castle was conquered.
The castle has lain in ruins since the bombardment by the British RAF on 21 and 22 February 1945, during Operation Veritable. In 2009, the property was purchased by the Bleijenbeek Foundation, which intends to restore the remaining structure, moat, and surrounding gardens and provide public access after work is complete. Construction began in the summer of 2012.
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.
