Wrangel Tower is named after Field Marshal F. E. H. von Wrangel. He arrived in Königsberg in 1809 as commander of the privileged Cuirassier Regiment. Wrangel Tower was built in 1843 as part of a defensive bastion of the ring of Königsberg. Water tower is surrounded by a moat, thick brick walls and ceiling to within three meters. Within 30 years, in connection with the development of long-range artillery, the construction of the tower was considered outdated, and in the early 20th century tower Wrangel was put out of the fortifications and to April 1945 in any military action did not participate.
During the assault of Königsberg during the World War II the tower was used as a base defense. April 9, 1945 the tower was blocked by Soviet troops, received minor damage and surrendered with the remnants of the Königsberg garrison. Now the tower hosts wholesale stores, warehouses and cafes.
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.
