"The Thang Long Imperial Citadel has become the 900th site to be inscribed on UNESCO’s World Heritage List. The Citadel was built in the 11th century by the Ly Viet Dynasty, marking the independence of the Dai Viet. It was constructed on the remains of a Chinese fortress dating from the 7th century, on drained land reclaimed from the Red River Delta in Hanoi. It was the centre of regional political power for almost 13 centuries without interruption. The Imperial Citadel buildings and the remains in the 18 Hoang Dieu Archaeological Site reflect a unique South-East Asian culture specific to the lower Red River Valley, at the crossroads between influences coming from China in the north and the ancient Kingdom of Champa in the south."

Hanoi is the site of "Thang Long" is old imperial capital of Vietnam. I visited this wonderful riverside city with strong Chinese, French and Vietnamese influenced architecture. Has many lakes that become a popular backpacker destination. The flag tower is where the old imperial city of Thang Long is located. I bought this postcard interestingly in Penang, not Vietnam. Then, I got this same postcard sent from Vietnam thanks to Jo. "Cam On" - thank you so much.
