The correct option is 1 and 3 only
Explanation
The Gol Gumbad is a prime example of the Deccan Indo-Islamic architectural style, specifically associated with the Adil Shahi dynasty of Bijapur (modern-day Vijayapura, Karnataka). It is renowned for its massive dome and acoustic features.
Statement-wise Analysis:
- Statement 1 is Correct: The Gol Gumbad is the mausoleum of Muhammad Adil Shah (1627-1657), the seventh ruler of the Adil Shahi dynasty. It also houses the tombs of his wives, daughter, and grandson.
- Statement 2 is Incorrect: The structure does not stand in isolation. It is part of a larger complex that includes a mosque, a Naqqar Khana (drum house), a gateway, and a dharmashala (guest house) located within a walled enclosure.
- Statement 3 is Correct: The dome of the Gol Gumbad is one of the largest domes in the world. It covers a massive square chamber with an area of approximately 1,700 square meters (over 18,000 square feet). This creates one of the largest uninterrupted floor spaces in the world, as the dome stands without the support of pillars.
Key Takeaway:
The Gol Gumbad is famous for its "Whispering Gallery," where even the softest sound echoes multiple times, and for possessing one of the largest single-chamber spaces covered by a dome without pillar support.
