St. Peter's Church, once three-naved, was built between 1227 and 1250 and expanded in the 15th and 16th century to a five-naved Gothic hall church. The church roof was destroyed during the Second World War and was provided with an emergency roof in 1960. Reconstruction was only completed in 1987.
Nowadays, St. Peter's is no longer used as a church. Instead, the 800-year-old light and airy church interior has evolved into a vibrant centre for events and exhibitions. A large arts and crafts market takes place here during the Christmas period.
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.
