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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
