Ochsenhausen Abbey was a Benedictine monastery was founded according a legend in the 9th century when there was a nunnery here called 'Hohenhusen', which was abandoned at the time of the Hungarian invasions in the early 10th century. A ploughing ox later turned up a chest of valuables buried by the nuns before their flight, and the monastery of Ochsenhausen was founded on that spot.
The first Abbey Church of Ochsenhausen was in fact dedicated in 1093. The monastery was initially a priory of St. Blaise's Abbey in the Black Forest, but gained the status of an independent abbey in 1391. In 1495 it became Reichsfrei (territorially independent).
The abbey was secularised in 1803 and in 1806 its territories were absorbed into the Kingdom of Württemberg.
Much of the buildings still survive. They were extensively refurbished in the Baroque style. The Baden-Württemberg State Youth Music Academy is accommodated in part of them. The former abbey church is now the parish church of St. George's.
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.
