St. John's Church in Petersdorf dates from the 13th century. Its 64-metre-high steeple was used as a daymark by ships on the Fehmarn Belt and Sound, as it is visible for up to 20 miles at sea. The church and adjacent cemetery are surrounded by 64 lime trees. The altar triptych dating from the 14th century is considered a masterpiece of Gothic carving skill. The oldest artefact is the font of Gotland limestone. The church also contains a particularly valuable 15th century altar shrine.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
