This Buddhist pilgrimage site containing relics of Gautama Buddha was constructed between the Mauryan and Gupta periods, according to research by Nepal’s Department of Archaeology.

A geophysical survey revealed a perfect quadrangular Kushan monastery buried below the surface, whose dense concentration of brick prevented crops from growing, leading to the area being known as an "unlucky field".

[19] King Dutthagamini then received from the Sangha the Buddha’s relics upon his head in a casket and departed from the golden pavilion in the midst of manifold offerings and honours made by gods and ‘‘Brahmas’’.

He circumambulated the relic-chamber three times, entered to it from the east, and when laid the relic-casket on a silver couch one ‘‘koṭi’’ worth, that was arranged in the north side.

When the enshrining of the relics in the Great Stūpa Ruvanveli was completed, the two novices Uttara and Sumana closed the relic-chamber with the stone-blocks that were previously hidden to be used as a lid.

The arhat Indagutta creates a metal canopy over the universe, so that Mara will not interfere, as monks chanted the Sutta Pitaka (the Collection of Discourses delivered by the Buddha).

Furthermore, by order of king Dutugemunu, the people of Srī Lanka enshrined, along with many other objects such as golden and silver caskets, thousand more of the Buddha's relics over the relic-chamber.

Graced by the Right Honorable Pushpa Kamal Dahal (Prachanda), the Prime Minister of Nepal, renowned architect Stefano Boeri unveiled the masterplan for the Conservation and Enhancement of the Ramagrama Stupa.
