The church of Santa Maria in Araceli is a late-Baroque style church built in the late 17th century in Vicenza according to designs attributed to Guarino Guarini. Construction of the present church was begun during 1672-1680, a period during which the famous architect Guarino Guarini resided in Vicenza under the patronage of the Theatines. In 1965, designs for the church were found in the Vatican Library. Construction seems to have been guided by Carlo Borella. It was about 60 years after the start of construction, on November 17, 1743, that the church was consecrated. In 1810, during the Napoleonic occupation, the convent was expropriated, and the church became a parish church.
The main baroque altar (1696), was carved in marble by Tommaso Bezzi . It contains an altarpiece representing the Tiburtine Sybil who portends the coming Virgin and Child to the Roman Emperor Augustus attributed to Pietro Liberi . The altar on the right has a 13th-century painted crucifix, originally from church of San Vito.
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.
