Da Vien islet

Da Vien Islet, a small island, which was officially named by King Tu Duc, facing the entry to the Hue Royal Palace. When building the Phu Xuan Royal Palace in the early 19th century, King Gia Long during the Nguyen Dynasty chose Da Vien as a White Tiger and Hen Islet as an Azure Dragon. The two powerful creatures was used to guard the emperors’ throne in the former Imperial City of Hue.
