San Juan y Todos los Santos (St John and All Saints) stands on the site of the former Convento de la Trinidad established shortly after Fernando III conquered the city in 1236. Built in the Baroque style, it forms part of the Historic centre of Córdoba.
It is believed the original church and convent were built on the site of a mosque although nothing remains of it. Nor are there any remains of the Church of San Juan de los Caballeros which remained after the convent was disbanded. There are however records of the roof collapsing in the 16th century and of its subsequent repair funded by Don Martin de Córdoba.
After the building again fell into disrepair, it was decided to build a completely new church which was consecrated on Trinity Sunday in 1705. The Baroque building is constructed in the form of a Latin cross with a nave covered by a barrel-vaulted ceiling decorated with painted lunettes. The dome above the transept is supported by pendentives. The church's artwork includes a figure of Christ the Saviour (Santo Cristo de la Salud) from 1590 carved by an anonymous author. It was brought from the former convent church of the Order of the Trinity (Orden Trinitaria) which used to be located in the Vía Crucis. Recent paintings from the nearby Cofrafía de la Santa Faz monastery include Nuestro Padre Jesús Nazerano by Antonio Dubé de Luque and María Santísima de la Trinidad by Antonio Salto.
The decorations surrounding the church's entrance contrast with its whitewashed facade topped with a triangular pediment and two oculi. The portal consists of a Romanesque arch flanked by double Doric columns with a frieze of triglyphs and metopes. The upper section with Solomonic columns contains group of sculptures in a niche with an angel in a Trinity robe assisting two captives. The square-shaped sacristy is decorated with several notable murals by Antonio Palomino (1653–1726). They depict scenes from the Old Testament associated with the Eucharist. The church's altarpieces are also decorated with a number of works from the 17th and 18th centuries.

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.
