All the Mughal architecture work consists of series of intricate patterns inscribed all over the buildings. You go to any place, be it the Taj Mahal in Agra, Red Fort & Jama Masjid in Delhi or Kutub Minar on the outskirts of Delhi, you can see the same art form prominently present all the places. It can be in the form of horizontal stripes or concentric circles or just scattered in different patterns on the floor and on the walls.
This pattern was one such example inscribed on the walls of a tomb in Red fort in Delhi.
