Discovering this Whispering Wonder of India wouldn’t be less than a majestic experience for anyone. Essentially a mausoleum of King Mohammed Adil Shah, who was the prosperous Sultan of Bijapur, this place is worth every ounce of your energy and time! This mausoleum was constructed in Vijayapura, Karnataka and the construction of this monument started in 1626 and got completed in 1656. As one can calculate, it took almost 30 years to construct this Deccan styled architectural marvel.
