The Seville Shipyard (Atarazanas) is a medieval shipyard. It was operative between the 13th and 15th centuries, and are built in Gothic style.
They were specialized in the construction of galleys, which played an important role in the struggles for the control of the Strait of Gibraltar, as well as in the Castilian participation in the Hundred Years' War. The complex consisted of a building with seventeen naves next to a large sandy area that reached to the edge of the Guadalquivir River.
Throughout its history, the building of the Royal Shipyard has undergone important transformations. At present, only seven of the seventeen original naves remain standing.
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.
