Architecture Features of Gol GUmbad

• Material: Built using robust dark gray basalt combined with ornate plasterwork.
• Measurement: The square building culminates in a grand dome, rising over 200 feet in total height, with walls each measuring 135 feet in length, 110 feet in height, and 10 feet in thickness.
  • The dome alone, with its impressive diameter of 125 feet, covers a vast 18,337 sq. ft, making it the second-largest in the world.
• Tomb’s Inner Sanctum
  • Royal Resting Place: The tomb chamber houses the memorials of the Sultan, his wives, and close relatives. 
    • However, their actual graves are discreetly located below in a basement chamber, accessible through stairs.
  • Structural Mastery: Achieving the vast dome over a square base required ingenious techniques. 
    • Pendentives played a dual role providing the dome its shape and distributing its weight to the walls. 
    • This mastery was further emphasized by the innovative use of arch-nets and stellate squinches for spanning intersecting arches.

• Acoustic and Aesthetic Innovations
  • Sound Dynamics: The whispering gallery, an acoustic marvel along the dome’s drum, can magnify and echo sounds repeatedly. 
  • Elevated Design: Four seven-storeyed octagonal spires, mimicking minarets, grace each corner of the Gumbad. These towers house staircases, providing access to the topmost section of the dome.
