Ton Duc Thang Museum The small, seldom-visited Ton Duc Thang Museum is dedicated to Ton Duc Thang, Ho Chi Minh's successor as president of Vietnam, who was born in Long Xuyen, An Giang province, in 1888. He died in office in 1980. Photos and displays illustrate his role in the Vietnamese Revolution, including a couple of very lifelike exhibits representing the time he spent imprisoned on Con Son Island.
