The Imperial Citadel of Thang Long (Vietnamese: Hoàng thành Thăng Long) was the cultural complex comprising Thăng Long Imperial City during the Lý, Trần, Lê dynasties and Hanoi citadel during the Nguyá»…n Dynasty. The remains are roughly where the Hanoi Citadel stands today. The royal palaces and most of the structures in Thang Long were destroyed in the late 19th century, and today the ruins of the Thang Long Imperial City are still being excavated. The central sector of the imperial citadel was listed in UNESCO's World Heritage Site on July 31, 2010 at its session in Brazil.[1] Activities: Product Launching, Gala Dinner, Award Ceremony, Concerts, Meeting, Wedding,
