Seckau Abbey was endowed in 1140 by Augustinian canons. An already existing community in Sankt Marein bei Knittelfeld was moved to Seckau in 1142. At the request of Archbishop Konrad I of Salzburg, Pope Innocent II instituted the founding of the congregation and the transfer to Seckau on 12 March 1143. The abbey church, a Romanesque basilica, was built from 1143 to 1164.
According to an old custom, the canons founded a double monastery. The women's chorus likely came to the abbey no later than 1150 from Salzburg, mentioned in a deed of the Noble Burchard of Mureck in 1150.
This establishment was dissolved in 1782. In 1883 the monastery was resettled by Benedictines from Beuron Archabbey, who had had to leave Germany because of the Kulturkampf. In 1940 the monks were evicted by the Gestapo and the buildings were confiscated. In 1945 the monks were able to return.
The abbey maintains a secondary school (Gymnasium) and carries out the duties of the pastoral care belonging to a parish.
The abbey church, a Romanesque basilica, was built between 1143 and 1164. For centuries it was the place of burial of the Inner Austrian line of the Habsburgs.References:
The Palace of the Grand Dukes of Lithuania was built originally in the 15th century for the rulers of the Grand Duchy of Lithuania. The Royal Palace in the Lower Castle evolved over the years and prospered during the 16th and mid-17th centuries. For four centuries the palace was the political, administrative and cultural center of the Grand Duchy of Lithuania.
Soon after the Grand Duchy of Lithuania was incorporated into Tsarist Russia, Tsarist officials ordered the demolition of the remaining sections of the Royal Palace. The Palace was almost completely demolished in 1801, the bricks and stones were sold, and the site was bowered. Only a small portion of the walls up to the second floor survived, that were sold to a Jewish merchant Abraham Schlossberg around 1800 who incorporated them into his residential house. After the 1831 uprising, the czarist government expelled Schlossberg and took over the building as it was building a fortress beside it. Before the Second World War it was the office of the Lithuanian Army, during the World War II it was the office of the German Army, and after World War II it was used by Soviet security structures and later transformed into the Palace of Pioneers. Fragments of Schlossberg's house have become part of the Eastern Wing of the restored Royal Palace.
A new palace has been under construction since 2002 on the site of the original building. The Royal Palace was officially opened during the celebration of the millennium of the name of Lithuania in 2009.
