According to tradition it was founded by Lý Anh Tông around 1160 after he visited a shrine to the Trưng Sisters, who then appeared to him as rain spirits. Culturally, the development of the cult of the sisters at that time is in the context of assertion of independence after the end of the Third Chinese domination of Vietnam - nearly 1000 years after the Qin conquest of Jiaozhi.
The altar display at the Trưng Sisters temple shows their violent death rather than suicide.
