Etching of the Pinnacle

A full scale replica of the pinnacle on top of the dome inlaid in the eastyern courtyard

This replica can be seen at the east at the foot of the riverside arch dubbed as Jawab alias Jamiat Khana (community hall).

The cocunut top and bent mangoleaves underneath, resting on a kalash (i.e.water pot) is a sacred Hindu motif.

Hindu shrines in the himalayan foothils have identical pinnacles.

The eastern location of the sketch is typically Hindu since east is of primordial importance in vedic culture.
Such floor sketches in courtyards are a common Hindu trait
