Henry V, Duke of Bavaria and his wife Luitgard erected a collegiate abbey of Augustinian Canons in his palace in Osterhofen in 1004–09. In 1017 the Emperor Henry II of Germany transferred the abbey to the diocese of Bamberg. In 1128 Bishop Otto of Bamberg brought men and women from the Premonstratensian Ursberg Abbey to the Osterhofen collegiate abbey.The abbey was endowed with extensive properties in the Wachau valley of Austria. The female branch of the abbey was probably extinct after 1200. In 1288 the head of the abbey become a provost. In 1414 the abbot was granted the right to wear the miter in liturgical celebrations.

Käser painting of fighting between Deggendorf and Vilshofen during the War of the Austrian SuccessionThrough its history, the monastery and the town had a checkered history, suffering damage from warfare and fire. There was a fire in the monastery in 1512. In 1701 a major fire caused by lightening destroyed the monastery. It was rebuilt in 1717–27. The former Gothic church also suffered great damage, and in 1726 it was decided to erect a new building. The fantastically ornamented monastery church was designed and built in 1726–40.
In 1783 the monastery was dissolved by the Bavarian state. Maria Anna Sophia, the widow of the Elector of Bavaria, wished to give the noble-born nuns of the convent of Saint Anne in Munich a better endowment. The Pope agreed to assign the monastery and its properties to the sisters. The last of the Premonstratensians remained in the building until 1800. The church became the parish church in 1818. The convent sold the monastery building to the state in 1833.
In 1858 the Sisters of Loreto moved into the building and founded a girls' secondary school. In 1859 it was designated a school for middle class girls to learn housework, and from 1859 to 1873 as an institute for neglected children. In 1886 it became a college of education. Care of small children began in 1901. The school started accepting day pupils in 1913. A dilapidated part of the abbey's west wing was demolished in 1938. In 1942 the school was temporarily closed, opening again in 1946.
The monastery church, built in colored stucco and marble, is one of the most lavishly decorated in Lower Bavaria. It was designed and built between 1726 and 1740 by the Munich architect and master-builder Johann Michael Fischer (1727–28) and the brothers Cosmas Damian Asam and Egid Quirin Asam. The nave is large, bright and spacious, with a 22 metres high ceiling. The Asam brothers created a throne room in honor of God. Cosmas Damian Asam, a brilliant painter, created the wonderful frescoes in the church. His brother Egid Quirin Asam filled the church interior with sculptures and ornaments, notably the impressive high altar. The altarpiece represents Saint Margaret set within a pagan environment, with a statue of Venus in a temple behind her. The church is considered a masterpiece of late baroque Bavarian church architecture. In 1983 the church became the Minor Basilica of St. Margaret, known as the Asambasilika.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
