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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
