Rheinstein castle was constructed around 1316-1317. It was important for its strategic location. By 1344, the castle was in decline. By the time of the Palatine War of Succession, the castle was very dilapidated. During the romantic period in the 19th century, Prince Frederick of Prussia (1794–1863) bought the castle and it was rebuilt.
In 1975 the opera singer Hermann Hecher bought the castle. It's due to him that Rheinstein Castle became again one of the centres of attraction in the Rhine Valley. Around the apartment tower from the 14th Century you find neo-Gothic sets, turrets, terraces and iron stairs. Inside are stained glass windows and mural painting as well as a Renaissance fire-place and stylish furniture.
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.
