The Castle Amerongen was built in 1673 on the site of a previous stronghold that had been burned in 1672 by the French.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.[1] Other ornaments were added in the early 20th century by P.J.H. Cuypers.[1] The gardens contain historical elements and the walls predate 1673.[1] Near the entrance bridge dating from 1678 is a wooden clock tower from 1728 that contains the original clock of the same date.[1] 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.[1] He abdicated in Amerongen then moved to Huis Doorn.
