Sagarhawa is the forest site where the ruins of an ancient pond were excavated in 1895. Sagarhawa is located about 12 km north of Taulihawa. Archaeologists have identified this site as the ‘Palace of the Massacre of the Shakyas’ by King Virudhaka the son of Prasenajita of the kingdom of Koshala. The ruins of the ancient site lie on the west and south banks of the large rectangular pond, which is locally known as Lumbu Sagar or long pond in then Niglihawa village.
