Some 20,000 Vietnamese prisoners died on Con Son and 1994 of their graves can be seen at the peaceful Hang Duong Cemetery, located at the northeastern edge of town. Sadly, only 700 of these graves bear the name of the victim interred within.
Vietnam's most famous heroine, Vo Thi Sau (1933–52), was buried here. She was the first woman executed by a firing squad in Con Son, on 23 January 1952.
Today's pilgrims come to burn incense and leave offerings at her tomb, such as mirrors, combs and lipstick (symbolic because she died so young). You may even encounter fruit and meals of sticky rice and pork.
In the distance behind the cemetery, you'll see a huge monument symbolising three giant sticks of incense.
