Château de Buchenek is a castle in the commune of Soultz-Haut-Rhin. Dating from the second half of the 13th century, it was altered, possibly in the 14th century, and in the 16th century.
The castle was first recorded in 1251. The logis, of a rectangular plan, possibly still dates from this period at the lower level; it was altered in the 14th century (there is evidence of building work) as well as in the second half of the 16th century (staircase tower). Restored after the Thirty Years' War, the castle was sold as national property. In the 19th century it was used as a factory. Bought by the town in 1976, the castle has had a significant restoration and, since 1990, has housed the municipal museum.
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.
