At the event, 32 photos with captions of the sea, rivers, and mountains across all regions of Vietnam, which were carved on the Nine Dynasty Urns (Cuu Dinh in Vietnamese language), were on display.

The bronze urns were cast in late 1835 and completed in early 1837, under the reign of King Minh Mang. They represent the unity and beauty of the country, as well as the aspirations for the immortal existence of the Nguyen Dynasty, according to the director of the Hue Monuments Conservation Centre, Hoang Viet Trung.

The urns, which remain intact, have been positioned in the yard of the citadel’s The To Mieu (To Mieu Temple), a place to worship the kings of the Nguyen Dynasty, since they were completed.

The highest urn is 2.5 meters high, while the shortest is 2.3 meters high. Each weighs up to 2,600 kg and has a name symbolizing an emperor of the Nguyen Dynasty.

Each urn was carved with 17 patterns featuring plants, animals, landscapes, and places of Vietnam.

The nine urns were recognized as a national treasure in 2012. The Hue Monuments Conservation Centre has also been taking steps to seek UNESCO recognition of them as a world documentary heritage.
