Nha lao Cay Dua. The Coconut Tree Prison. It is the gentlest name any prison has ever been given, and the prisoners used it themselves - partly because coconut palms genuinely did crowd the wire, partly because on this island there was nothing else to name a place after. The French built it in 1949 and 1950 across roughly forty hectares near the southern end of Phu Quoc, as somewhere to put Vietnamese who would not accept French rule. Fifteen years later the Republic of Vietnam took the same idea and multiplied it. By 1972 the camp covered more than four hundred hectares of the An Thoi valley and held over thirty thousand prisoners of war, the largest such camp in South Vietnam. The site is a museum now. The queue forms in the same heat, under the same trees.
The first prisoners here were political - men and women detained by a colonial administration fighting to keep an empire it had already lost. Nearly fourteen thousand passed through the French camp. Ninety-nine died. In its first year alone around two hundred got away, which says something about both the determination of the detainees and the improvisation of the place; this was wire and huts on a remote island, not a fortress. Phu Quoc had a particular logic for jailers. It lies far off Vietnam's southwestern coast, closer to Cambodia than to Saigon, with open water in every direction. A man who cut his way out was still on an island. The French left in 1954, and the coconut grove sat quiet for a time before the next war filled it again.
South Vietnam reopened the site in late 1955 and rebuilt it wholesale in 1966, when the war's prisoner numbers outgrew everything that existed. The result was less a prison than a small administrative city devoted to confinement. Twelve zones stood by 1972, with zones 13 and 14 added late that year. Each zone was designed for about three thousand men and split into four sectors - A, B, C and D - holding roughly nine hundred and fifty apiece. Sector B2 was reserved for officers, none ranking above major. The population was not what the phrase 'prisoner of war' usually conjures. Around twelve thousand were regular soldiers; more than twenty thousand were local militia and political cadres, meaning village people who had been swept up alongside the fighters; over two thousand were officers. Counting every era, some forty thousand people were held on this ground.
The International Committee of the Red Cross reached Phu Quoc in 1969 and again in 1972, and its delegates recorded what independent observers could see plainly: prisoners showing the effects of insufficient food, medical care that barely existed, and beatings. Vietnamese survivors and the museum's own archive go considerably further, and their testimony is specific in the way that only lived experience is. Men describe being forced into chuong cop kem gai, barbed-wire cages set out in the open sun, where no position was possible that did not draw blood. Others describe a diet of rice served without salt for months, which by the fifth or sixth month took their sight. Teeth were broken out. Needles were driven beneath fingernails. More than four thousand people died here in the six years between June 1967 and March 1973, and tens of thousands more left carrying injuries they never lost - blindness, deafness, hands that no longer worked. They had been farmers and radio operators and teenagers from villages a few hundred kilometres away.
Nobody inside accepted the arrangement quietly. Prisoners cut fences and dug tunnels through sandy soil with whatever they could hide, and the war outside pressed against the wire from the other direction; the camp was shelled or attacked thirty-four times in 1968 alone. An American study of prisoner-of-war policy records that during the Tet Offensive that year 2,665 prisoners broke out through the fenceline, and that few of them were recaptured - a figure so large that it reads less like an escape than a collapse. What finally emptied Phu Quoc was diplomacy rather than tunnelling. The Paris Peace Accords of January 1973 required the exchange of prisoners, and through the spring the zones were cleared. The site was abandoned for good when the war ended in April 1975.
In 1995 Vietnam designated the ground a national historic site, later elevating it to a special relic of national significance. A monument shaped as a clenched fist rises above the trees. Beside it lies a martyrs' cemetery for the dead, and behind that stand reconstructed barracks, watchtowers and cages, populated with figures arranged in the postures survivors described. It is not a subtle museum, and it was never meant to be. What gives the place its peculiar force is the geography: this is Phu Quoc, an island now selling itself hard as a beach destination, and many visitors arrive at the gate with sand still on their feet. They come out quieter than they went in. The palms overhead are the same species the prisoners named the place for, and they are still, unhelpfully, beautiful.
Phu Quoc Prison lies at 10.044N, 104.018E, on the flat coastal plain of the An Thoi valley at the southern end of Phu Quoc island, about 4 km north of An Thoi town and its naval harbour. From the air the museum grounds read as a pale rectangular clearing set back from the east coast road, with the reconstructed barracks laid out in regular rows and the fist monument casting a long shadow in early light. The historic camp footprint - over 400 hectares at its greatest extent - is far larger than the preserved section. Phu Quoc International (VVPQ/PQC) sits at 10.172N, 103.991E, elevation 36 ft, roughly 15 km north; approaches from the south pass almost directly overhead. Recommended viewing altitude 2,000-4,000 ft. Clear conditions prevail November to April; the southwest monsoon from May to October brings rain, haze and low cloud over the island's interior ridge.
