The construction of the tomb was started on September 4th, 1920 and lasted for 11 years. The overall construction of the tomb is an emerging rectangular structure with 127 steps, leaning against the mountain.- Entering the tomb area, one should climb a 37 steps gate with the biggest dragons in the country forming the side walls. In the courtyard, line two rows of left and right altar built according to traditional configuration of "double storeys with eight roofs", but all the rafters are made of reinforced concrete.

Climbing 29 further steps, one is reaching the imperial audience court, in the centre of which stands the octagonal stele monument also made of reinforced concrete. On both sides of the courtyard, two rows of statues are facing towards the court center. In addition to these statues, similar to those of the other tombs, there are six more couples representing bodyguard soldiers.

These statues are made of stone, a material very rare in Khai Dinh's tomb. The courtyard is flanked on both sides by two high and imposing pillars. Visitors have to go up three more levels in order to reach the altar monument. The Khai Thanh Palace is the main room of the Thien Dinh Palace, which contains many connecting rooms. The walls are densely decorated and inlaid with elaborate glass and porcelain designs. The floor is covered with enameled flowers bricks and the ceiling is painted with nine dragons, appearing in fine fleeting clouds. 

The rear room of the Khai Thanh Palace constitutes the main temple, which contains the statue of Khai Dinh, his grave and his altar. The tomb of Khai Dinh is one of the most surprising among the royal tombs of Hue.
