The Cathedral of Cartagena is located on the hill of La Concepción in the old town of Cartagena. It has been in ruins since 1939, when it was destroyed when Cartagena was shelled in the Spanish Civil War by Nationalist forces.
Cartagena had a see before the Muslim conquest of Spain, but no trace of the pre-conquest cathedral has been found yet. In 1243 Alfonso X of Castile launched a campaign to reconquer the Kingdom of Murcia, and petitioned Pope Innocent IV to restore the Diocese of Cartagena. In 1250 the Pope issued the bull 'Spiritus exultante' restoring the diocese. The first bishop of the new phase of the Diocese was the Franciscan friar Pedro Gallego, Alfonso's confessor.
There is inconclusive evidence whether there was a cathedral in Cartagena at that time. In medieval and Renaissance documents the church is described as Iglesia Mayor, and is only called 'Old Cathedral' from the eighteenth century.
García Martínez, the second bishop of the diocese, decided with the consent of King Sancho IV to transfer the see to Murcia, although retaining the name of Diocese of Cartagena. The church therefore lost its status of a cathedral, and became a parish church.
Throughout the centuries, there were continuing demands to the Vatican for the restitution of the bishopric to Cartagena. The church of Santa María de Gracia, with the shape and dimensions of a cathedral, was built in the 18th century on a different site, with the aim of becoming the seat of the diocese in place of the original church.
In the late nineteenth century the foundations of the medieval church collapsed. The church was restored by the architect Victor Beltrí, in Romanesque style with modernist elements.
During the Spanish Civil War the church was attacked and the contents damaged on 25 July 1936. In 1939 it was bombed and has remained abandoned since then.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
