Which cathedral is the largest Gothic cathedral in the world by area?

Seville Cathedral is the largest Gothic cathedral in the world by area.

Known formally as the Cathedral of Saint Mary of the See, it was built in Seville after 1401 on the site of a large Almohad mosque. Rather than erasing the earlier complex completely, the Christian builders incorporated important Islamic remains, most notably the Giralda, the former minaret converted into the cathedral's bell tower, and the Patio de los Naranjos.

The Gothic section is enormous, measuring roughly 126 meters long and 76 meters wide, with a central nave about 36 meters high. The cathedral's scale reflects Seville's wealth and importance after the Christian conquest of the city in 1248.

A common mix-up is confusing “largest Gothic cathedral” with “largest church.” St. Peter's Basilica is larger overall, but it is a Renaissance and Baroque church rather than a Gothic cathedral. Area comparisons can also vary depending on whether measurements include courtyards, attached spaces, or only the Gothic core; Seville remains the conventional answer for this trivia question.
