The citadel in Huế

Construction of the citadel began in the early 1800s. Originally the wall was made of earth, then a covering of bricks was added. It took tens of thousands of Vietnamese to do this by hand.
During the 1968 Tet offensive there was heavy fighting in Hue, and much of it was concentrated in the area of the citadel. Consequently much of it was damaged. And because of economic difficulties there has been little resoration until quite recently, however work is not underway in may areas, and tourist interest can only help with this.
