The Sassenpoort is a gatehouse in the citywall of Zwolle, Netherlands. It was build in 1409 after Zwolle city became a member of the Hanseatic League in 1407. The city gates represent the wealth of this period. In the period between 1893 and 1898 restoration work took place. The dormers were made, and a neogothic spire clock tower was installed, replacing an earlier 18th century spire. In between the corner towers is a machicolation. From holes in the floor of this outer work, boiling oil could be thrown at enemies. The gatehouse is a rijksmonument since 1967 and is part of the Top 100 Dutch heritage sites. The gate now serves as a pedestrian road.
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.
