Kangura is a decorative pattern found directly above the molding at the top of many Mughal facades that has an alternating pattern to appear like fortification crenellation or "battlements."1 At Humayun's Garden Tomb, the kangura pattern is an optical illusion of repeated stylized floral crenellation that plays with perception of positive and negative space using the contrast between white marble and red sandstone. This bold white and red kangura can be found on the tops of the hammam, the baradari, and Humayun's Tomb. A monochrome sandstone variation of the red and white kangura can be found at the top of the West Gate, The South Gate, and The Barber's Tomb.
