Gol Gumbaz is a fabulously imposing structure, towering 51 meters above the surrounding city of Vijayapura and representing one of the most important examples of late-medieval Indo-Islamic architecture. Meaning “circular dome”, it is appropriate that this mausoleum is most famous for its massive crowning feature — which is not only architecturally impressive, but also houses a sonic funhouse.With a diameter of 44 meters, the dome of Gol Gumbaz ranks among the largest domes of the pre-modern world and is supported by a series of interlocking arches without any columns.
