Jever castle dates back to a weir from the late 14th century. The fortress got its typical characteristics mostly from the massive keep, which during the 15th and 16th century was surrounded by a Vierseitanlage. When Jever became part of the Duchy of Oldenburg in 1818, the castle was declared an auxiliary residence of the Dukes of Oldenburg and the now useless outbuildings and fortification were done away with. The museum has been situated in the castle since 1921 and features collections of cultural history, folklore and the archaeology of the Jever region.
The historic rooms also give an overview of the lifestyle of the 16th to 19th century. You will have the best view from the 67 meter-high castle tower. The viewing platform offers a unique view over the expanse of the Friesian coast.
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.
