Kristineberg Palace in Kungsholmen was built around 1750 for the businessman R. Schröder. The palace was surrounded by parks and the property included a great deal of the surrounding land. In 1864 the property was bought by the Swedish Freemasonry and additional construction on the palace was made. Stockholm City bought the land in 1921 and started building the Kristineberg district, and today part of the palace is used as a school.
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.
