Holy Spirit Church was was built in late Baroque style in the mid-18th century by the Protestants, who were dispossessed of St. Mary’s Church as a result of the Tumult of Toruń in 1724. The slender church tower was added in the end of the 19th century. Today the church is a university church affiliated with Nicolaus Copernicus University. The most finest details in the church are the mid-18th century Rococo high altar and the beautiful door with intarsia on the axes of the aisles near the presbytery, depicting Christ’s death and resurrection.
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.
