Located at the foot of the Palatine Hill, Santa Maria Antiqua is the oldest and most significant Christian monument in the Roman Forum. The church was abandoned in the 9th century after an earthquake buried the buildings; it remained sealed for over 1000 years until its rediscovery in the early 20th century. Therefore, Santa Maria Antiqua represents a key element for the understanding of the cultural and urban development of the Roman Forum from Antiquity into the first centuries of the Christian period. Following a conservation program, the church is now open for tours.
The church contains a unique collection of wall paintings from the 6th to late 8th century. The discovery of these paintings have given many theories on the development of early medieval art and given distinctive beliefs in archaeology. The church has the earliest Roman depiction of Santa Maria Regina, the Virgin Mary as a Queen, from the 6th 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.
