An exhibition on the Thang Long royal citadel and the Ho Dynasty citadel was held in Hanoi on October 10 to popularise and highlight the global values of Vietnam’s two world-recognised heritages.

On show were over 100 documents, sketches, images and artifacts that helped visitors have an insight on the construction materials and architectures of the two citadels.

Thang Long, now Hanoi, was the capital of the country of several dynasties while the citadel built in the present-day central province of Thanh Hoa was the capital of the short-lived Ho Dynasty in the last years of the 14th century and the first years of the 15th century.

The same day, a symposium on the same theme was held with reports focusing on the preservation and efforts to bring into full play the values of the two heritages.-VNA
