Hang Duong Cemetery is a shrine to 20,000 national heroes of the country who died when they were imprisoned or were executed. The most respected among these national heroes is the grave of Vo Thi Sau - a 14-year old martyr who took up arms against the French Resistance at a tender age. Her sacrifice is revered and respected among the locals who come here to pay homage to the freesom fighter.
The cemetery, located in Con Son, also has a massive structure that symbolises three burning incense sticks, a ritual to pay obeisance to the ones buried here. Another famous burial that took place at this tomb of the brave was that of Nguyen An Ninh - A Vietnamese writer and an activist in the revolution. A large number of Vietnamese come to Con Dao, not to enjoy the splendid beaches, but to pay their respects to the national heroes buried in this cemetery.
