The stupa was constructed during the reign of King
Parakramabahu the Great. According to the
Mahavamsa, the great chronicle of Sri Lanka, the stupa was built by Bhaddavatī (Subhadra), one of Parakramabahu's queens. It was originally known as the
Rupavati Chetiya or
Rupavati Thupa. The current name,
Kiri Vehera, which translates to "Milk Stupa," was likely given later due to the brilliant white colour of its lime plaster finish that survived for centuries. After the fall of the
Kingdom of Polonnaruwa in the 13th century, the city was abandoned and became overgrown with dense jungle. The Kiri Vehera remained hidden for centuries until it was rediscovered by British explorers in the 19th century. When it was found, the stupa was in an exceptional state of preservation, with its original lime plaster largely unharmed by the centuries of neglect and exposure to the elements. == Architecture ==
