The origins of Hernen lie to the west of the present castle, next to the river Elst. That is where the first motte castle of Hernen was sited, and remained in use until the 12th/13th century. This was possibly also the fortress of the Lords of Hernen, who first appear in the records in 1247. The lord received income through taxes and special privileges, such as the milling rights. This income enabled him to extend his castle, which in turn increased his status.
Around that time, Hernen was partly in Cleves and partly in Gelderland. In the 14th century, work started on the construction of the present castle, which was sited on the Gelderland part. Later, everything came again under one estate. The east wing and the monumental entry gate date from 1555. A special feature is the covered patrol path - quite rare in the Netherlands.
The castle never suffered war damage or natural disasters. In the last century, the lord of the castle hardly ever lived there, leaving the administration to a steward. There was no urge to embellish the castle according to the latest fashion in architecture, and consequently the castle was able to keep its austere, medieval character.
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.
