The Kreuzkirche was designed by architect Arthur Kickton and built between 1930 and 1933 for the evangelical community of Königsberg. Between the two towers a monumental cross from Kadyny maiolica is situated. The church was only lightly damaged in World War II and became a garage and a factory for fishing equipment thereafter. After a fire it was decided in 1988 to use the building as a church again, now for the Kaliningrad Orthodox community. Both towers were connected to the nave again in the restoration that followed. The original clock of the church now hangs on the Church of the Holy Family.
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.
