Seville Cathedral and Giralda Tower

This is the world's largest Gothic cathedral by volume, built on the site of Seville's great mosque between 1401 and 1506. The scale hits you immediately: the nave soars 42 meters high, and the Capilla Mayor houses the world's largest altarpiece, an 80-year golden masterpiece that dominates the space. Columbus rests here in a tomb held by four bronze kings, and the attached Giralda Tower (the original minaret) offers panoramic views from 70 meters up.

The visit flows from overwhelming grandeur to intimate discovery. You'll crane your neck at vaulted ceilings, then find yourself studying intricate chapels tucked into corners. The Giralda climb uses ramps instead of stairs, making the ascent surprisingly comfortable. At the top, 360-degree views stretch across Seville's rooftops, the Guadalquivir River, and the sprawling Andalusian landscape beyond.

Most guides don't mention that the main entrance queue can stretch for blocks, especially after 10 AM. Entry costs EUR 12 for both cathedral and tower, but buy online and use the Puerta de San Cristóbal entrance on the south side to skip the chaos. The cathedral closes Mondays, and Sunday mornings are for worship only. Plan 90 minutes minimum, but you could easily spend half a day here.
