On the afternoon of April 26th, at Tang Tho Lau (Archive Pavilion) inside Hue Imperial City, Hue Monuments Conservation Center organized the “Exploring and Promoting the value of the Documentary Heritage: The relief castings on the Nine Dynastic Urns at Hue Imperial Citadel” event in celebration of Vietnam Book and Reading Culture Day 2025.

Although Hue is a land known for its numerous national-scale libraries and archives, the work of Tang Tho Lau (or Tang Thu Lau - Archive Pavilion) - also known as Lau Tang Tho (or Tang Thu), is still considered a rare “Treasure of the Ancients” of the monarchy period that has been remarkably preserved.
