Sacra Capilla del Salvador is a famous chapel, built between 1536 and 1559, is the flagship of Úbeda Renaissance architecture. Commissioned by Francisco de los Cobos y Molina as his family's funerary chapel, it presents a marked contrast between the relatively sober proportions of the interior (by Diego de Siloé, architect of Granada's cathedral) and the more decorative western facade. The facade, a pre-eminent example of plateresque style, was designed by Andrés de Vandelvira, one of Siloé's stonemasons, who took over the project in 1540.
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.
