The letter says there are three kinds of bricks which nowhere match size and shape of the original ancient bricks of the stupa.
"The stupa has been completely covered with new bricks, leaving no traces behind of its original bricks and construction material," the letter says. Gauri has alleged the binding material used for the bricks is cement and sand, which are prohibited in the renovation of ancient monuments.
There were four cardinal points and niches to place idols but now they appear as stairs.
There were traces of approximately 52 pits around the parikrama path but they have been covered under the path.
They were two feet deep and wooden pillars used to be placed in them to create a boundary around the stupa.
