The Roman theatre of Verona should not to be confused with the Roman amphitheatre known as the Verona Arena. The theatre was built in the late 1st century BC. Before its construction, two walls were built alongside the Adige River, between the Ponte di Pietra and the Ponte Postumio, to protect it against floods.
Today only remains of the edifice are visible, recovered starting from around 1830. They include the cavea and the steps, several arcades of the loggias and remains of the stage. Part of the cavea was occupied by the church of S. Siro, built in the 10th century and restored in the 14th century. At the top of the hill there was an ancient temple, built on a series of terraces.
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.
