The first small Starhemberg castle was built by Ottokar III, Margrave of Styria between 1140 and 1145. At the time, the Piesting river was the border between Styria and the March of Austria. In 1192, Styria—and, thus, the castle—was acquired by the Babenbergs. The last Babenberger duke of Austria, Frederick II the Warlike, expanded and fortified the castle, leaving Starhemberg as one of the most important castles in Lower Austria in the 13th century. In wartime, the archives and the family treasure was hidden here, and were guarded by the Teutonic Knights.
After the Battle on the Marchfeld in 1278, the castle was acquired by the Habsburgs. In 1482, the castle was captured by Matthias Corvinus, king of Hungary. In 1683, the castle offered protection from the Turks to the surrounding population.
To escape a new roof-tax the counts of Heusenstamm around 1800 had the roof covering removed, as well as doors and window frames, beginning the decline of the castle. Around 1870, a large part of the great hall collapsed. Until the mid-20th century, the ruins were used for the extraction of construction materials by the local population.
In the spring of 1945 a unit of the Waffen-SS used the ruined tower above the chapel as an observation post. Russian artillery fire inflicted heavy damage to the walls.
In the second half of the 20th century a local organisation, Friends of the Castle Starhemberg, has sought to restore the ruins. Since 2007, the castle has been closed to visitors, for security.
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.
