Huwiler Tower (Huwilerturm) is the smallest of the four outer town wall towers in the city of Zug (Switzerland). Its exact age is unknown, but cannot be later than 1524/25. The tower was known for a long time as the 'Hof' tower, and was called that until it was acquired by a citizen named Huwiler (a.k.a. Huwyler) in 1697. Huwiler tower was part of the defense system and the city wall, but as Zug was actually never under siege.
In 1870 the tower was auctioned and purchased by a private owner. Today the Huwiler tower stands in the pleasant surroundings of the art museum gardens.
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.
