Santa Marina is one of the so-called 'Fernandinean Churches', edificated in the city after Ferdinand III of Castile conquered it from the Moors in the 13th century. The structure combines proto-Gothic, Mudéjar and, to a lesser degree, late-Romanesque elements.
The church, one of the oldest of the Fernandinean group, was built in the second half of the 13th century where previously a Moorish mosque and before that a 7th-century Visigothic church had existed. No trace of them remains today.
On 23 June 1880 the church suffered a fire, which required a restoration lasting two years. Other renovations were carried out in the 19th and 20th centuries, during which the medieval appearance of the building was restored, by removing the Baroque additions introduced after the damage from the 1680 and 1755 earthquakes.
The church has a rectangular, or basilica, plan, divided into a nave and two aisles, the nave being far higher than the latter. The aisles are separated from the nave by large pointed arches.
The facade is characterized by four large, asymmetrical buttresses, ending with pinnacles, and corresponding to the interior separation between nave and aisles. Also present are a main central rose window, smaller circular windows, and alfizes over the ogival arch of the main portal. The facade corresponding to the left aisle features a secondary portal, surmounted by a triangular arch.
The apses are polygonal. In the right aisle is the sacristy, built in the 15th century. The left aisle apse was adapted to house a Baroque chapel from 1630. The bell tower dates to the 16th century.
The 'retablo' of the Main Chapel houses paintings by Antonio del Castillo and sculptures from the local artist Gómez de Sandoval.
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.
