Bijapur officially known as Vijayapura, is the district headquarters of Bijapur District of Karnataka state. It is also the headquarters for Bijapur Taluka. Bijapur city is well known for its historical monuments of architectural importance built during the rule of the Adil Shahi dynasty. Bijapur, the land of five rivers and the domain of different cultures, is an ancient city. The city established in the 10th and 11th centuries by the Chalukyas of Kalyani was known as Vijayapura (City of victory). Bijapur was the biggest district place of the state with 11 taluks, but after forming Bagalokote new district in 1997 Now it consists of five taluks viz. Basavan Bagevadi, Bijapur, Indi, Muddebihal and Sindagi. The city was established in the 10th-11th centuries by the Kalyani Chalukyas and was known as Vijayapura (City of victory). The city was passed to Yadavas after Chalukya's demise. The city came under the influence of the Khilji Sultanate in Delhi by the late 13th century. In 1347, the area was conquered by the Bahmani Sultanate of Gulbarga. By this time, the city was being referred as Bijapur. In an introduction to an album of Bijapur published in 1866, Philip Meadows Taylor wrote: “Palaces, arches, tombs, cisterns, gateways, minarets, ...all carved from the rich basalt rock of the locality, garlanded by creepers, broken and disjointed by peepul trees, each in its turn is a gem of art and the whole a treasury.” This is the most famous monument in Bijapur. It is the tomb of Mohammed Adil Shah (ruled 1627-1657). It is the largest dome ever built in India, next in size only to St Peter's Basilica in Rome. A particular attraction in this monument is the central chamber, where every sound is echoed seven times. Another attraction at the Gol Gumbaz is the Whispering Gallery, where even minute sounds can be heard clearly 37 metres away. Gol Gumbaz complex includes a mosque, a Naqqar Khana (a hall for the trumpeters) (Now it is used as museum) and the ruins of guest houses.
