Holsteinborg Castle was built by the Trolle family between 1598 and 1651, but has been owned by the Holstein family since 1707. The first count, Ulrich Adolph Holstein, established ten village schools on the estate in about 1710. The first Christmas tree in Denmark was lit at Holsteinborg in 1808, Northern Europe's first savings bank was opened in 1810 and Denmark's first health insurance was available in 1811. Between 1810 and 1825, a total of 14 schools and 12 handicraft schools were built on the estate. Hans Christian Andersen was inspired by his many visits to the castle, where he wrote some of his fairytales, stories, songs, poems and accounts of his travels.
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.
