The largest and oldest church of the Zutphen is the St. Walburgis (Saint Walpurga) church, which originally dates from the 11th century. The present Gothic building contains monuments of the former counts of Zutphen, a 14th-century candelabrum, an elaborate copper font (1527), and a monument to the Van Heeckeren family (1700).
The chapter-house of library contains a pre-Reformation library which includes some valuable manuscripts andincunabula. It is considered one of only 5 remaining medieval libraries in Europe (the other 4 being in England and Italy). The old books are still chained to their ancient wooden desk, a habit of centuries ago, dating from the times when the library was a 'public library' and the chains prevented the books from being stolen.
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.
