[citation needed] In the eleventh century, the Waithali Kingdom declined, giving way to the Lemro period of Arakanese history.
Most, including Parein, lay on the western lowland shores of the Lemro river with their walls disappearing over the course of time.
In Arakanese legend and chronicle, the nat Mra Swan is the lady guardian spirit of Parein.
The shrine is built in the middle of fields with the statue of Mra Swan facing west towards the location of the old palace.
The revival of worship sites for minor nats within Mrauk-U Township, like the shrine in Parein, may be a way in which Burmese military officers attempt to gain symbolic recognition by drawing on the historical involvement of the Bagan Kingdom in the Lemro Valley's history.
