Rastede Castle is a castle at Rastede near Oldenburg, Germany. It was a residence of the rulers of Oldenburg. It is now owned by Christian, Duke of Oldenburg.
The town of Rastede is about 12km north of Oldenburg and houses the magnificent Castle of Rastede. It was the home of Counts and Dukes of Oldenburg and is still lived in by their descendants. It is, therefore, not open to the public. It is in a public park, so you can walk around it.
It began its life as a monastery but was transformed by Christopher, Count of Oldenburg. Anthony Günther, Count of Oldenburg, had large stables built in 1612. The former monastery was demolished in 1643 and replaced by a new hunting lodge, which was used as a summer residence.
