The islands were a prison site for decades. The French opened a prison in 1862, and many Vietnamese political prisoners were held and died here. The camps, including Phu Hai Camp, were used again after 1954.

After 1975 the prisons were turned into memorials. Today the islands are also a protected national park known for turtles, reefs and forest.
