The Amphitheatre of Mérida is situated in the Roman colony of Emerita Augusta, present-day Mérida, in Spain. The city itself, Emerita Augusta, was founded in 25 BC by Augustus, to resettle emeritus soldiers discharged from the Roman army from two veteran legions of the Cantabrian Wars (the Legio V Alaudae and Legio X Gemina). The amphitheatre itself was completed in 8 BC. The term emeritus refers to the soldiers, all of whom had been honorably discharged from service.
The amphitheatre had a capacity of approximately 15,000 spectators and had supporting stairs and hallways (scalae) that connected the different parts internally.
The amphitheatre is part of the Archaeological Ensemble of Mérida, which is one of the largest and most extensive archaeological sites in Spain. It was declared a World Heritage Site by UNESCO in 1993.
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.
