Its upward-reaching lines seem to rise endless as the boat gets nearer, until they merge into its protective shield of palm trees in front, the old quarter houses behind it, and the colorful fishing boats and their undulating reflection in the calm waters of the bay.

The Seo, as it is called here, was build on the site of a pre-existing Arab mosque. One night in 1229, as Jaime I was on his way to recapture Majorca, his fleet was struck by a terrible storm. He vowed the and there to the Virgin Mary that if he survived nature’s fury, he would erect a church in her honour. And after the storm had blown over, finding himself safe and sound, he immediately undertook the project. It was a vow that was to take an inordinate amount of time to fulfil. begun in 1230, the cathedral was finished in 1601.

The port-side facade features another door, a true masterpiece of Spanish Gothic. It is called the "Mirador portal", or "Puerta del Mar", and is the collective work of such celebrated artists as Pedro de Moret (who sculpted the statue of the "Virgin with Child", the original of which is housed in the Diocesan Museum) and Juan de Valenciennes (who created the "Last Supper" and the "Trinity"), among others. The most important of all these artists is Guillermo Sagrera, who concentrated the refined nuance of his art-work into the two statues of Saint Peter and Saint Paul that flank the portal. The vast, airy interior is striking for its large-scale harmonious proportions. It features three naves resting on 44-meter tall octagonal pillars, eight chapels each side of the nave, and lacks both transept and ambulatory. The rear interior reveals the majestic "Royal Chapel", which is nearly as large as a church in its own right: 25 meter long and 16 meter wide. The main altar, consecrated on October 1, 1346, is surmounted by one enormous "wrought-iron chandelier", forged by Antoni Gaudi as if it were the baldaquin for the altar.

Behind it, we see 110 breathtaking walnut choir-stalls sculpted in flaming Gothic style and, to left, a noteworthy "Renaissance pulpit" by J. de Salas. On a slightly higher level at the back of the choir-stalls, the "Chapel of the Holy Trinity" reveals the ancient tribune of the kings of Majorca and a sort of present-day pantheon for the same: in fact, it houses the sepulcher containing the mummified body of Jaime II and a 1948 Gothic-style tomb by Federico Marés with the ashes of Jaime III, the last in the line of the short-lived but glorious Majorcan dynasty.
