Emperor Dong Khanh was born in 1864, crowned in 1886 and breathed his last only 3 years later in 1889 at the age of 25. He was also Emperor Tu Duc’s nephew and foster-son.

Since the reign of Emperor Dong Khanh, in other words, after the fall of the capital city of Hue (5 July 1885), Vietnam completely surrendered her independence to France. In his daily life, the Emperor took to wine, perfume, using alarm-clock, etc. imported from France.
Emperor Dong Khanh died young, having no time to start his tomb construction. Most of the monuments of the tomb were simply planned and built during the first year of Emperor Thanh Thai’s reign (1889), repaired, improved and complete in the years 1916, 1917, 1921 and 1923 under Emperor Khai Dinh (Emperor Dong Khanh’s son).
The tomb has 20 monuments, both principal and secondary. Like those of three preceding Emperors (Thieu Tri, Tu Duc and Duc Duc), Emperor Dong Khanh's tomb is divided into two areas, the tomb and the temple, 100m apart.
The Ngung Hy Temple, dedicated to the cult of Emperor Dong Khanh and his two Ladies, is the monument of greatest value of art. Most noteworthy are the building materials and decoration. Aside from the elaborate exterior decoration, the interior is lacquered red gilded and richly adorned. It is the best conserved and most splendid monument of Hue.

As a whole, Emperor Dong Khanh's Tomb is pretty, delicate and bears to some extent the cross – cultural stamp of European and Asian civilizations in late 19th-early 20th centuries.
