The Church of Our Lady was initially dedicated to St. Michael. Its original form dates from the year 1439, and in the 17th century it was restored. Hence its exterior and interior are significantly baroque.
Next to the central altar from the 18th century, there is a painting of Mary with the Child. The church is richly decorated with four paintings representing the stages in the life of St. Augustine. They were initially attributed to F. Fontebasso, but today they are considered to be the work of G. Agnelli, a pupil and successor of the great Piazzeta. The wall intarsia and the wooden frame, made by the Venetian carver Brustolone, are also worth mentioning.
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.
