The first mention of the Tongelaar Castle on this site dates from 1282 when it was dedicated to Count Floris V by Jan van Cuyk. The Van Cuyk family was probably owner of the castle until somewhere in the 15th century when it was owned by the Van Merwick family. In later centuries ownership of the castle passed through several noble Dutch and Belgian families until the 20th century.
The only medieval part of Tongelaar Castle is the square brick tower. This was originally the gate tower and would have been equipped with a drawbridge. The large window would have been the entrance. This tower dates back to the early 15th century. Archeological research proved that there had been a fortified medieval building at the opposite side of the gate tower but that they had not been connected by walls with each other. The tower would have had several living quarters and had a prison below ground level.
All the other present buildings were built in the 18th and 19th century. The western wing was either built on the foundations of an earlier building or built with the use of old building materials.
The tower is now a corner tower of a closed square farm with a simple courtyard.
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.
