The restoration of the bell tower, now standing as a twin to the drum tower, was not a matter of modern steel and glass. Instead, the Hanoi Handicraft and Village Association looked to the wood-carvers of Son Dong and the bronze-casters of Ngu Xa. These men and women are the living repositories of a architectural language that dates back to the 11th century, when Emperor Ly Thai To first directed the construction of this imperial seat upon the remains of a 7th-century fortress.
For decades, the citadel was a place of absences. During the French colonial administration, the primary wooden and brick structures were systematically leveled to make way for military barracks. It was only through the luck of the spade that the site’s true depth was revealed; in 2002, workers preparing the ground for a new National Assembly building struck the foundations of ancient roads and buried ceramic artifacts, prompting a massive archaeological effort.
The significance of this restoration lies in the movement of the hands that built it. By rejecting large-scale institutional contractors, the project allowed descendants of the original builders to apply their hereditary knowledge to the UNESCO World Heritage Site. They worked with the weight of thirteen centuries beneath their feet, in a place where terracotta well shafts built from overlapping pots still sit in the earth.
As the Thang Long – Hanoi Heritage Conservation Centre takes stewardship of the towers, the landscape of the citadel feels less like a ruin and more like a recovery. The bell and drum now stand as physical evidence that while a building can be demolished, the specific geometry of its construction—the way a joint fits or a bell is tempered—survives within the families of the valley.
