The Altenstein Castle, located in Franconia, was once the seat of the lords of Stein zu Altenstein. The castle had its origins in the Teufelsstein, a rock castle that stood below Lichtenstein Castle. The Steins of Lichtenstein had their seat at the castle of Lichtenstein, while the Altensteins became vassals of the Prince-Bishops of Würzburg.
The castle, mentioned indirectly in 1225 and directly in 1231, developed into a Ganerbenburg, occupied and managed by several branches of the family. It had a significant role in the early record of joint inheritance. The Altensteins established a small territory around the castle during the 14th and 15th centuries, consolidating their scattered lands.
The castle faced damages during the Peasants' War in 1525, but in 1549, Emperor Charles V granted the high court jurisdiction to the Altensteins. The family faced a decline in fortunes and conflicts, including the execution of William of Stein zu Altenstein in 1567. The castle was sacked during the Thirty Years' War, and the family eventually moved to a new schloss in Pfaffendorf.
The castle fell into ruin over time and was donated to the district of Hassberge in 1972. The site underwent renovation and development, becoming accessible to visitors. The castle ruins, located on unstable subsoil, require ongoing stabilization measures. The castle chapel, originally built in 1438, had to be rebuilt and underwent further changes over the years.
Today, the Altenstein Castle is part of the Haßberge Castle Educational Path and offers a circular walk around the inner ward, allowing visitors to explore the ruins and previously inaccessible areas.
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.
