Being one of welknown lakes in Hanoi, Truc Bach Lake has its own meaning of not only landmarks but also history
Formerly, Truc Bach Lake and West Lake joined to each other. Until 1620, it was separated from the West Lake by the construction of a narrow dike Co Ngu (now is Thanh Nien Road). In the 18 century, the Lord Trinh Giang had a palace constructed on the lake shore which first served as a pleasure palace but was later converted into a prison for royal concubines found guilty of crime who had to made silk to live themselves. The silk they produced, known as “Bamboo Village Silk”.
On the lake there’s a small hill-up on which a temple was built called Cau Nhi Temple (it’s no longer now).
On October 26, 1967, US Navy aviator John McCain was shot down and parachuted wounded into Truc Bach Lake, nearly drowning. He was dragged out of the water by city residents.
