Seville Cathedral.

Seville Cathedral is a stunning blend of Gothic, Moorish, and Renaissance styles, built on the site of a former Almohad mosque. As the largest Gothic cathedral in the world, it features the iconic Giralda bell tower, a former minaret that offers panoramic city views. The cathedral's vast interior showcases 68 ogival vaults, an impressive altarpiece, and the tomb of Christopher Columbus, surrounded by artistic contributions from masters like Murillo. The layout preserves elements of the mosque, including the tranquil Patio de los Naranjos. This UNESCO World Heritage Site remains an active place of worship, highlighting its ongoing cultural and religious significance in Seville.
