In the article "World Cultural Heritage Hue Monuments - 20 Years of Looking Back" by Prof. Dr. Luu Tran Tieu commented: "The beauty of Hue architecture is not necessarily the splendor and grandeur of the scale. scale, but rather the measure of structure, appearance, harmony, and harmony between architectural works and the natural landscape environment". Like the tombs of previous kings such as Gia Long, Minh Mang, Thieu Tri, Tu Duc, Dong Khanh's Tomb has a harmonious beauty between natural elements and contrasting architecture, sophisticated from the hand. works of ancient artists.
Regarding architectural model, Dong Khanh mausoleum has about 20 large and small architectural works with relatively thick density. The impregnated area turns to the southeast, right in front of it is a semicircular lake planted with lotus to serve as an "enlightenment" element, and Thien An hill, about 3km away, is used as a "convict".
The general structure of Dong Khanh mausoleum is not much different from other tombs: facing East - Southeast, taking Thien Thai mountain as the front; Bai Dinh courtyard has rows of traditional statues of mandarins, Tru Bieu, Bi Dinh, and Buu Thanh. But from architecture, and decoration to building materials, almost all are "Europeanized". If the statues of the mandarins at Tu Duc Tomb are carved in stone with a too-low body size, on the contrary, the statues of the mandarins in Dong Khanh Tomb are covered with lime brick with a tall but thin figure using ardoise tile. In particular, Bi Dinh (where the stele is erected) has Western Neoclassical architecture mixed with traditional Asian styles, close to the later architecture of Emperor Khai Dinh mausoleum.
