Hue, capital of the Nguyen dynasty, is unique with the mausoleums of its 19th-20th century kings. Some of these tombs have been rehabilitated thanks to UNESCO funds.
The tomb of Gia Long (r. 1802-1820)--the founder of the dynasty--, is the least visited and the farthest from Hue: 15 miles south. It building complex is also the most neglected because the communist regime does not like king Gia Long, which it considers to have "brought in the snake--the French--that killed the chicken." In reality, the communists are the real "snakes" because having brought in the Chinese to support them during the war, they have become indebted to them. In exchange, they have ceded patrimonial territories to them, including the Paracel Islands (which were under South Vietnam control in 1974, see Pham van Dong September 14, 1958), border lands with China, etc... They have also let the Chinese exploit bauxite in the highlands without strict regulation resulting in serious environmental disaster. Illegal Chinese, workers and otherwise, have been brought in to do the work at the expense of local Vietnamese.
