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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
