Iglesia de San Nicolás de Bari is located next to the Camino de Santiago, in front of the cathedral. Since the Church of San Esteban was turned into a museum, it has served as the seat of the parish of San Esteban. The church was built in 1408, replacing another Romanesque temple. It contains notable examples of fifteenth century Castilian Renaissance art by Simón de Colonia and his son Francisco. Also of great interest are the Gothic tombs, and the Renaissance arc by María Sáez de Oña and Fernando de Mena.
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.
