The Cathedral of Saint Mary of the See, better known as Seville Cathedral, is a Roman Catholic cathedral in Seville, Andalusia, Spain.
It was registered in 1987 by UNESCO as a World Heritage Site, along with the adjoining Alcázar palace complex and the General Archive of the Indies. It is the fourth-largest church in the world (its size remains a matter of debate) as well as the largest Gothic church.
After its completion in the early 16th century, Seville Cathedral supplanted Hagia Sophia as the largest cathedral in the world, a title the Byzantine church had held for nearly a thousand years.
The total area occupied by the building is 11,520 square metres (124,000 sq ft). The Gothic section alone has a length of 126 m (413 ft), a width of 76 m (249 ft), and its maximum height in the center of the transept is 42 m (138 ft).
The total height of the Giralda tower from the ground to the weather vane is 104.5 m (342 ft 10 in).
