The city of Mérida returned under Christians hands in 1230, when it was conquered by Alfonso IX of León. The city was attached to the Archdiocese of Santiago de Compostela. The construction began on a chapel dedicated to Virgin Mary on the ruins of the Visigothic cathedral.
In 1479, Don Alonso de Cárdenas, Master of the Order of Santiago, ordered the extension of the chapel with the intention to make it the main church of the city. In 1620, a bull of Pope Paul V creates the title of titular bishop of Mérida. The bishop was chosen among the priests of the Order of Santiago, that chose the church of Santa María as see of their bishopric.
In 1994 Pope John Paul II established the Archdiocese of Mérida-Badajoz, making the Church of Saint John Baptist his metropolitan cathedral and co-cathedral the church of Saint Mary Major of Mérida.
The cathedral is rectangular in shape and consists of three naves (the central one is two times wider than the lateral ones), separated by square pillars, with a detached column on each face upon which pointed arches are alighted. The roof of the auditoriums was originally of a Mudejar style ceiling but is now vault shaped.
The high altar consists of two sections. Covered with a vault of tierceron, the first is on a rectangular base and the second on a spectrum, with keys decorated with a rosette plant and the Mystic Lamb. On both sides of the presbytery, under arcosolia, the tombs in alabaster of Don Diego de Vera Mendoza, of the Order of Santiago and his wife Doña Marina Gomez de Figueroa can be admired. The central apse is decorated with a large altarpiece from 1762, which two bodies surround a 13th-century window.
The central vaulted niche of the second body, which rests on a pedestal base, is occupied by an image of the Virgin Mary, accompanied by the apostles Peter and Paul and the local saints Eulalia and Julia.
Among the apsidal chapels, the Chapel of the Epistola, of the Earls of la Roca, is the most notable. It is divided into two sections and both covered with ribbed vaults, decorated with their shield.
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.
