Falkenstein Castle is located at 1,268 metres above sea level and it is Germany's highest located castle. The stone castle was built approximately 1270–1280 by Count Meinhard II von Tirol on the borders of his land (Tyrol). Because of the unusual situation of the castle it has been interpreted in historical context as a symbol of opposition to the Duchy of Bavaria. The name Castle Falkenstein only came into use in the 15th century. The castle was largely destroyed in the 17th century.
King Ludwig II of Bavaria purchased the ruin in 1883 and commissioned several architects, the first being Christian Jank (the designer of Neuschwanstein), to replace the existing structure with a romantic castle. Jank first created a restrained design, but later envisioned the castle in a dramatic, High Gothic style. Georg Dollmann was employed to produce plans and elevations in the same year based on Jank's design. However, his modest and economical designs displeased Ludwig.
Ludwig died in 1886 before work on the castle proper could begin, and the many plans for Falkenstein were permanently abandoned. The ruin of Castrum Pfronten on the building site was never demolished.
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.
