St. John the Evangelist's Church in Paczków, Poland, is a Gothic church built in the fourteenth-century. The construction began in the year 1350 and lasted around 30 years. The shrine was funded by Bishop of Wrocław Preczlaw of Pogarell, who administered between 1341 and 1376. The present form of the church is in the Renaissance, Baroque and Neo-Gothic architectural styles. In the fifteenth-century, from the chancel's southern side, there was built a spanning chapel, dedicated to Holy Virgin Mary. The tower, partially deconstructed in 1429, was rebuilt in 1462. It was then that the upper condignation was constructed.
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.
