The Royal Basilica of San Francisco el Grande is a Roman Catholic church in central Madrid. The main façade faces the Plaza of San Francisco, at the intersection of Bailén, the Gran VÃa de san Francisco, and the Carrera de san Francisco. It forms part of the convent of Jesús y MarÃa of the Franciscan order. The convent was founded in the 13th century at the site of a chapel.
The basilica was designed in a Neoclassic style between 1761 and 1768, based on a design by Francisco Cabezas, developed by Antonio Pló, and completed by Francesco Sabatini. The church contains paintings by Zurbarán and Francisco Goya. The temple once functioned as the National pantheon and enshrined the remains of famous artists and politicians.
The dome is 33 metres in diameter and 58 metres in height; its shape is very similar to the Pantheon's dome, having a more circular shape than the typical domes built in the 18th century.
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.
