The Triumphal Arch is a Roman structure in the city of Orange. There is debate about when the arch was built, but current research that accepts the inscription as evidence (27 BC-AD 14) favours a date during the reign of emperor Augustus. It was built on the former via Agrippa to honor the veterans of the Gallic Wars and Legio II Augusta. It was later reconstructed by emperor Tiberius to celebrate the victories of deceased general Germanicus over the German tribes in Rhineland (c. 20–27 AD). The arch contains an inscription dedicated to emperor Tiberius in AD 27.
Along with the Roman Theatre of Orange, the Triumphal Arch was inscribed on the UNESCO World Heritage List in 1981 because of its exceptional preservation.
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.
