• The mausoleum has the smallest area but the longest construction time
Overall, the mausoleum is a rectangular floating block reaching 127 steps high, with Thien Dinh Palace as the center. Mountains, hills, and streams of a large area around the Mausoleum are used as feng shui elements: front, back, left dragon, right tiger, clear path, and water convergence, giving Khai Dinh mausoleum a majestic natural landscape.
Compared to the mausoleums of the previous kings, Khai Dinh mausoleum has a much more modest area, with the size of 117 m × 48.5 m, but it is extremely elaborate and time-consuming.
• The only mausoleum with East-West cultural interference
To build the mausoleum, Khai Dinh ordered people to France to buy iron, steel, cement, and Ardoise tiles..., ordered boats to China and Japan to buy porcelain, glassware, and color crystals... to construct buildings on this hill.
