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:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
