Originally begun by Ferdinand III on the site of a former mosque, the cathedral was largely rebuilt by Andrés de Vandelvira, architect of Jaén's cathedral, between 1570 and 1593, though the west front has architectural influences from an earlier period. A fine 14th-century rose window crowns the 13th-century Puerta de la Luna (Moon Door). Don't miss the baroque silver monstrance (a vessel in which the consecrated Host is exposed for the adoration of the faithful), which
is carried in Baeza's Corpus Christi processions—the piece is kept in a concealed niche behind a painting, but you can see it in all its splendor by putting a coin in a slot to reveal the hiding place. Next to the monstrance is the entrance to the clock tower, where a small donation and a narrow spiral staircase take you to one of the best views of Baeza. The remains of the original mosque are in the cathedral's Gothic cloisters.
