Dâu Temple, also known under formal names: Diên Ứng (延應寺), Pháp Vân (法雲寺), and Cổ Châu, is a major Buddhist temple in Thanh Khương commune, huyện Thuận Thành, Bắc Ninh Province. Located some 30 km east of Hanoi, the temple historically marks the ancient settlement of Luy Lâu, once an important center of Buddhism in Vietnam. 500m farther away lies the Temple of Sĩ Nhiếp, the remarkable Chinese Governor of Jiaozhi at that time.
