The event was organized by the Thang Long - Hanoi Heritage Conservation Centre.

At the seminar, experts discussed measures and solutions to continue expanding research at the relic site as well as improving international cooperation to promote its cultural and historical value.

A host of treasures hidden beneath and left on the ground over 1,300 years earned the core of the Thang Long Imperial Citadel UNESCO recognition as a world cultural heritage site in 2010.

The site encompasses the No. 18 Hoang Dieu archaeological site and the central axis of the Hanoi ancient citadel, which are nestled in the Forbidden Area in the heart of Thang Long Imperial Citadel.

Many architectural vestiges of palaces, pavilions, and the foundations of architectural structures of the Imperial Citadel have been uncovered.
