Rosenstein Palace was built between 1822 and 1830 by the court builder Giovanni Salucci (1769–1845) in the classical style for King Wilhelm I. The palace stands in Rosenstein Park on a height overlooking the Neckar river valley. Formerly called the Kahlenstein (literally 'bald rock', because it was bare of trees), the hill was renamed Rosenstein ('rose rock'), and a rose garden was planted to the south-east of the palace.
Today, Schloss Rosenstein houses that part of State Museum of Natural History Stuttgart dealing with extant lifeforms.
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.
