The location of ancient Kapilavastu is still not unanimously accepted. Indian guidebooks and historians consider Piprahwa to be the real Kapilavastu, while Nepalese guidebooks and historians consider Tilaurakot to be the real Kapilavastu. A compromise is to regard Tilaurakot as the 'old' Kapilavastu and Piprahwa as the 'new' Kapilavastu. Another view is that Kapilavastu is a large area which is mainly in Nepal but partly in India.
The Archaeological Survey of India carried out an excavation between 1971 and 1977, at Kapilavastu. Of the stupas and inscription of Kushana period excavated from the site, one stupa was referred to as the Eastern Stupa by the archaeologists.
