Arvfursten Palace (Arvfurstens palats) is located at Gustav Adolfs Torg in central Stockholm. Designed by Erik Palmstedt, the palace was originally the private residence of Princess Sophia Albertina. It was built 1783-1794 and declared a historical monument in 1935 and subsequently restored by Ivar Tengbom in 1948-52. Since 1906 the palace has served as the seat of the Ministry for Foreign Affairs.
The palace is facing the square Gustav Adolfs torg, with the Royal Swedish Opera on the opposite side. Located near the palace are the Sager Palace, official residence of the Prime Minister, and Rosenbad, official office of the government. The bridge Norrbro stretches past the Riksdag on Helgeandsholmen and further south to Stockholm Old Town and the Royal Palace.
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.
