The Castle Amerongen was built in 1673 on the site of a previous stronghold that had been burned by the French troops during the invasion of 1672. The current building was designed by the architect Maurits Post as a baroque palace for the owners Godard Adriaan van Reede and his wife Margaretha Turnor. In the main hall a central staircase with painted ceiling was built by Willem van Nimwegen. Other ornaments were added in the early 20th century by P. J. H. Cuypers. The gardens contain historical elements and the walls predate 1673.
Near the entrance bridge dating from 1678 is a wooden clock tower from 1728 that contains the original clock of the same date. In the north-east corner of the gardens is an orangerie dating from the 1880s, and the north wall was raised during the period when Wilhelm II was residing there 1918-1920. He abdicated in Amerongen then moved to Huis Doorn.
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.
