The peepal tree under which she offered the Kheer is an important theme.

A stupa dedicated to her has been made in the village

Sanchi, is famous in the world for stupa.

It was discovered in a ruinous condition and restored by Cunningham

This was built by Emperor Ashok as a religious centre at Sanchi perhaps because he was fascinated by the location of the hill or because of his Queen Devi, who was the daughter of a merchant of Vidisha.

He erected the Great Stupa (Stupa 1) here after redistribution of mortal remains of Lord Buddha for erecting several stupas all over the country in order to spread Buddhism.

This stupa was originally a low structure of brick, half the diameter of the present edifice hemispherical in shape with raised terraces at the base.

It was enclosed by a wooden railing and a stone umbrella at the top. This Great Stupa served as a nucleus to the large Buddhist establishment during the later period.
