Gol Gumbaz, located in the Bijapur district of Karnataka, is renowned as the largest dome in India and an architectural marvel of the Deccan Sultanate. Built in 1656 by Sultan Muhammad Adil Shah, the dome has a striking diameter of 124 feet, making it the second largest in the world after St. Peter’s Basilica in Rome. With a floor area of 1,700 square meters and a height of 51 meters, the structure is supported by walls that are 3 meters thick, remarkably constructed without the use of pillars.

This monumental edifice houses the tombs of Muhammad Adil Shah, his two wives, his mistress, his daughter, and his grandson. Gol Gumbaz is especially celebrated for its exceptional acoustics; even the slightest whisper made within the dome reverberates multiple times, earning it the title of a "whispering gallery." The seamless blend of scale, balance, and acoustic design marks Gol Gumbaz as a masterpiece of Indo-Islamic architecture and a symbol of Karnataka’s historical legacy.
