Blutenburg Castle is an old ducal country seat in the west of Munich. The castle was built between two arms of the River Würm for Duke Albert III, Duke of Bavaria in 1438–39 as a hunting-lodge, replacing an older castle burned down in war. The origin of this castle is a moated castle of the 13th century. The core of this castle was a residential tower, the remains of which were uncovered in 1981. The fortress was first mentioned in writing only in 1432.
Albert's son, Duke Sigismund of Bavaria, ordered extensions of the castle beginning in 1488; he died here in 1501. The main building became derelict during the Thirty Years War, but was rebuilt in 1680–81. The castle is still surrounded by a ring wall with three towers and a gate tower. The defensive character of the castle, however, was with the reconstruction in 17th Century significantly reduced. The plant was already at that time no longer defensible.
Sigismund of Bavaria also ordered the construction of the palace chapel, a splendid masterpiece of late Gothic style which still has preserved its stained-glass windows, along with the altars with three paintings created in 1491 by Jan Polack. The cycle of the statues of the apostles on the side walls was built around 1490/95.
Since 1983 the International Youth Library (Internationale Jugendbibliothek) has been housed in Blutenburg Castle. The Blutenburg concerts are well known.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
