Cathedral of Murcia:

When the Christian king Jaime I the Conqueror conquered the city, in spite of the existing pact with the muslims of the city that prevented destroying any mosque, the king Jaime I took the Great Mosque or Aljamía to consecrate it to the Virgin Mary, since he had the custom to offer a mass to Our Lady whenever he conquered a village. The cimentation of the cathedral begun in the 13th century, in the same place where the great mosque stood. In 1385 the laying of foundations began and in 1388 the first stone was laid. But it was not until 1394 that the construction began, which would be finished in October 1467. Nevertheless, the cathedral continued to grow until the 18th century, which means that the cathedral is made of a variety of artistic styles.
