Falkenstein Castle in the Weinviertel region of Lower Austria was founded around 1050 by Emperor Henry III. 1106 Leopold III, Margrave of Austria purchased the castle, from then on it was owned by the rulers of Austria. 1572 Maximilian II sold Falkenstein to the Baron (later Count) of Trautson.
In 1645, in the last period of the Thirty Years' War Falkenstein was conquered by Swedish forces, but not destroyed. Its decay began at the end of the 17th century, when the castle was dismantled by the owners themselves in order to re-use the material.
During the summer season, the inner ward is turned into an impressive site for medieval feasts and theatre plays.
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.
