The Royal Tobacco Factory, an 18th-century industrial building was, at the time it was built the second largest building in Spain, second only to the royal residence El Escorial. It remains one of the largest and most architecturally distinguished industrial buildings ever built in that country, and one of the oldest such buildings to survive.
Since the 1950s it has been the seat of the rectorate of the University of Seville. Prior to that, it was, as its name indicates, a tobacco factory: the most prominent such institution in Europe, and a lineal descendant of Europe's first tobacco factory, which was located nearby. It is one of the most notable and splendid examples of industrial architecture from the era of Spain's Antiguo Régimen.
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.
