In 1356, an earthquake damaged the mosque, leading to its eventual replacement by the cathedral. Construction of Seville Cathedral began in 1402 and took over a century to complete, finishing in 1506[1][2]. The architects, including Diego de Riaño and Martín de Gainza, designed the cathedral to be "so beautiful and so great that those who see it built will think we were mad"[2].
The cathedral retained elements of the original mosque, such as the Giralda bell tower and the Patio de Naranjas. Today, it is the largest Gothic cathedral in the world, featuring an impressive central nave and eighty chapels[1][3]. The tomb of Christopher Columbus is a major tourist attraction, symbolizing Seville's historical connection to the New World[1][3].
