The Gol Gumbaz in Bijapur, Karnataka, India was constructed between 1626-1656 AD to serve as the tomb of Mohammed Adil Shah. The massive structure measures 47.5 meters on each side and is capped by a dome that is 44 meters in diameter. Eight intersecting arches support the dome and help create the monumental interior space, with sound carrying clearly across the 37 meter diameter main hall.
