About This Dataset
Largest Church Buildings in the World by Interior Area
Church size is normally quoted as interior floor area, the space actually enclosed under the roof, rather than the footprint of the whole complex. This chart ranks the world's largest church buildings by interior area in square metres.
Analysis
St. Peter's Basilica in Rome is the largest church building in the world with 25,616 square metres of interior space, 1.02 times the 25,000 of Cathedral Basilica of Our Lady Aparecida. The 12 churches here enclose 164,697 square metres between them, and St. Peter's Basilica alone accounts for 16% of that. These are buildings from very different centuries: the list mixes Renaissance basilicas with twentieth-century cathedrals, and the smallest entry shown, Cathedral Basilica of Our Lady of the Pillar, still covers 8,318 square metres - larger than most football pitches.
