A little more perspective
The basilica’s own dimensional reference gives 136.57 meters from the base to the top of the cross. Its more general size answer rounds the building to 136 meters; this record preserves the explicit cross endpoint.
The lantern, sphere and cross are visible above the main dome. Comparing the dome roof alone would omit this upper assembly. The surrounding square and its colonnades are outside the bounded basilica illustration.
