Gol Gumbaz is the tomb of king Muhammad Adil Shah (1601-1656), seventh ruler of Bijapur. The tomb is located in Bijapur, Karnataka, India.

Bijapur, officially known as Vijayapura, is the district headquarters of Bijapur District of Karnataka state. The city was established in the 10th-11th centuries and was known as Vijayapura (city of victory). Bijapur came under Muslim influence, first under Allaudin Khalji, the Sultan of Delhi, towards the end of the 13th century, and then under the Bahamani kings of Bidar in 1347.

The city hosts the country's largest and the world's second largest dome, Gol Gumbaz, a work of architectural genius. Unsupported by any pillars, this mausoleum was completed 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.

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 Bijapur's most important tourist spot but also invites visitors from all corners of the world.
