The church of Sant'Eufemia is an ancient church in Verona. A church at the site was likely present by the 11th or 12th centuries, although the main layout we see today was completed only in the 14th century. In the interior, altarpieces were completed by Brusasorci and Giovanni Domenico Cignaroli. In the 14th century Spolverini chapel, there is a canvas and frescos by Giovanni Francesco Caroto. The gothic belltower contains six bells in F rung with the Veronese bellringing art.
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.
