Gothenburg Cathedral (Gustavi domkyrka or Göteborgs domkyrka) lies near the heart of the city. The cathedral was built in 1815 and replaced an earlier cathedral built in the 17th century. The architect was Carl Willhelm Carlberg. The cathedral is a fine example of neoclassical architecture. It is one of the top tourist destinations in the city. The Cathedral acts as a venue for a wide range of classical concerts and recitals, as well as hosting regular services.
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.
