Much debate surrounds the construction of Sri Ksetra. Htin Aung suggests that Pyu might have been founded in 78 CE, based on the Sanskrit / Pyu Era. D. G. E. Hall and Gordon Luce, however, claim that civilisation of the Irrawaddy Valley could not have been possible before the 4th century, thus, attributing the founding of Sri Ksetra to 638, from which the current Burmese Kawza Era begins.
Sri Ksetra was the capital of the Pyu dynasty of Vikrama. The city was circular with walls enclosing about 46 km2 (18 sq mi), making it the largest walled city in south-east Asia during its peak. The city contained both housing and also farms, as evident from the remains of water ways and tanks which have been discovered.
The Chinese pilgrims Xuanzang and Yijing mentioned about Sri Ksetra in their mid-7th-century accounts. It is not known when precisely the Pyus abandoned Sri Ksetra and moved northward. It is speculated that their decline was due to the growth of the Irrawaddy river delta, cutting it off from coastal trade, and also from Mon and later Tai Shan incursions. Burmese chronicles state that when Anawrahta invaded the southern parts of modern-day Myanmar in 1057, he ordered the ruins of Sri Ksetra to be destroyed to prevent rebels from sheltering. The Burmese came to call the old Pyu center Pyi. The extensive ruins have been the subject of intensive archaeological investigation.
