The country's largest and the world's second largest dome, Gol Gumbaz is a work of architectural genius. Unsupported by any pillars, this mausoleum of Muhammed Adil Shah was constructed in 1656 by architect Yaqut of Dabul. It attracts thousands of tourists every year and has seven-storeyed octagonal spires with heavy bracketed cornice right below the parapet. The structure is an acoustic wonder as the whispering gallery can echo the faintest of whispers for a total of 11 times. The dome finds it name from 'Gom Gummata', derived from 'Gol Gombadh', which means circular dome. It reflects the Deccan style of architecture. The tomb is a giant cube that is topped with a hemispherical dome. Each storey of the structure has seven arched windows that are crowned by smaller domes. Surrounded by beautiful lush green gardens, the monument is not only Vijayapura's most important tourist spot but also invites visitors from all corners of the world.
