The building of the Cigognier, the largest sanctuary on the site (35m x 17m) began in the year 98 AD. Analysis of the wooden stakes beneath the building's foundations allowed this date to be established. The plans, technology and materials used are inspired by Rome. It was a rectangular building with a courtyard framed with porticos. Only the priests had access to the room that contained the worshipped statue. The faithful gathered in the courtyard, where processions also took place. This division of spaces demonstrates the hierarchical organisation of society at that time.
The discovery, in 1939, of a gold bust of Marcus Aurelius in one of the sanctuary's pipes, suggests that this portrait of the emperor was used as an image of worship. This magnificent object, composed of a single gold leaf of over 1.5 kg and dating from the 2nd century, is now preserved at the city's Roman Museum.
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.
