The Cathedral of Burgo de Osma is in the Gothic architectural style, and was constructed on an area previously occupied by a Romanesque church. It is one of the best preserved medieval buildings in the country and considered one of the best examples of thirteenth-century gothic architecture in Spain. The building of the church started in 1232, and was completed in 1784. The cloister is from 1512. The tower is from 1739. The cathedral is dedicated to the Assumption of Mary.
The latest additions are from the 18th century although the cathedral was built over a primitive 13th-century Romanesque temple, reason why there are so many interesting elements to see such as the main façade and its Renaissance-style door, its high tower, the altarpiece and the Gothic marble pulpit in the major chapel. Other works of art are the frescos in the dome, the Immaculate figure on the central altar which was brought from Rome, the Neoclassical sacristy, the Flamboyant Gothic cloister, beautiful stain glass windows on the upper part of the cathedral or the tomb of San Pedro de Osma, which is considered a masterpiece of funerary art. Inside the cathedral, there is also a museum with paintings and sculptures, as well as valuable codices such as the one known as “El Beato”.
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.
