Gol Gumbaz is the monumental tomb in Bijapur famous for its enormous unsupported dome.
The mausoleum is in Vijayapura, formerly called Bijapur, in the Indian state of Karnataka. It was built as the tomb of Mohammed Adil Shah, who ruled the Adil Shahi Sultanate from 1627 until 1656. Construction began during his reign and the building was completed after his death.
The central chamber is covered by a dome measuring about 44 metres in external diameter. The dome rests on interlocking arches and pendentives rather than on interior columns, leaving a vast unobstructed space below. Four octagonal towers rise at the corners, and each tower contains stairways leading to galleries.
A famous feature is the Whispering Gallery, where quiet sounds can travel around the gallery beneath the dome. Gol Gumbaz belongs to the Deccan Sultanate tradition and is not a Mughal monument, a distinction often missed in general discussions of Islamic architecture in India.
