The ruins of the Kronenburg and the almost completely preserved Burgbering from the 13th century still leave their mark on the village today. In the 18th and 19th century the castle fell into disrepair. Of the main building only two semi-circular towers of the north gate and the ruins of the keep can be seen. The dimensions of the original grounds are recognizable from the the remains of the surrounding wall and of a semi-circular Bastion. There are also remains of the working quarters in the courtyard, situated further down.
Next to the Bergbering the well-preserved and restored half-timbered houses are worth visiting. The greatest attraction for sight-seers is the late-gothic parish church of St.John, with its interior. It was built around 1500, included in the wall surrounding the castle. As there is only one buttress in the middle to hold up the fine vault, it is called a single support church.
References:The Royal Palace was built in the first half of the 19th century as the Norwegian residence of King Charles III, who also reigned as king of Sweden and otherwise resided there, and is the official residence of the present Norwegian monarch. The crown prince resides at Skaugum in Asker west of Oslo. The palace has 173 rooms.
Until the completion of the Royal Palace, Norwegian royalty resided in Paleet, the magnificent town house in Christiania that the wealthy merchant Bernt Anker bequeathed to the State in 1805 to be used as a royal residence. During the last years of the union with Denmark it was used by the viceroys of Norway, and in 1814 by the first king of independent Norway, Christian Frederick.
