Gol Gumbaz, situated in Bijapur is an astounding engineering feat. Its
enormous "Whispering" dome is second in size only to St. Peter's
Basilica in Rome. The dome is the second largest in the world, 124 feet in
diameter.The dome stands unsupported by pillars. The fantastic acoustical system in the dome carries the faintest whisper around the dome and returns it to the listener nine times.
Even the tick of a watch or the rustle of paper can be heard across a distance of 37 m in the whispering gallery. The gallery around the dome provides a fabulous view of the town.
The architecture of this building is unique with the four minarets being the four staircases leading to the top dome. The beauty and excellence of this dome must be experienced at least once in a lifetime.
