The Đakovo Cathedral or Cathedral basilica of St. Peter is the cathedral of the Roman Catholic Archdiocese of Đakovo-Osijek.
Đakovo Cathedral is the biggest sacral newly built building of Croatian historicism. The St. Peter Cathedral in Đakovo is the town's most famous landmark and the most important sacral object.
The cathedral was built 1866-1882 under Josip Juraj Strossmayer, who was the bishop of the Catholic diocese of Đakovo and Srijem. The architects of the cathedral are Carl Roesner and Friedrich von Schmidt from Vienna. Fresco paintings depicting scenes from the Old Testament in the nave and the New Testament scenes from the life of St Peter in the chancel were executed by the Roman painters of German origin Alexander Maximillian and Lodovico Seitz, except for two frescoes which were painted by Achille Ansiglioni. The scenes from the life of St Peter were partially made according to the drawings created for Đakovo Cathedral by one of the leading Nazarene painters Friedrich Overbeck.
The landscaped park from the 19th century near the bishop's palace is a horticultural monument under special protection as well as the nearby Small Park (Mali Park) dating from the turn of the 19th/20th century.
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.
