Airstrips swallowed by jungle, a thick silence, and the clearest sea in the Pacific all around: Tinian is like no other port of call. This island in the Northern Marianas, neighbour of Saipan, has barely 3,000 residents gathered around San Jose, its only town. Ships, mostly expedition vessels, anchor off the harbour built by the US Navy Seabees during the Second World War. It was here, on this speck of coral, that one of the heaviest chapters of modern history played out.

North Field and the atomic bomb pits

The north of the island is home to North Field, which was briefly one of the largest air bases in the world: four runways of nearly 2,600 metres, kilometres of taxiways and parking areas designed for hundreds of B-29 bombers. It was from here that the Enola Gay took off, loaded over a specially dug pit, now protected by a glass canopy and marked by commemorative signs. The two atomic bomb loading pits can be visited freely, surrounded by interpretive panels, amid cracked slabs where vegetation is slowly reclaiming its ground. The site imposes no message: it confronts each visitor, in silence, with what left from here in August 1945.

Traces of the battle

Around the runways, remains older than the pits survive: Japanese bunkers, gutted command buildings and the beaches of the 1944 American landing. Vehicle excursions tour these sites in a few hours, with commentary. Underwater, the area around the harbour also hides wartime remains, aircraft wrecks and equipment, which divers explore in remarkable visibility. History here isn't read in a museum: it surfaces everywhere, between the vines and the coral.

The House of Taga

Long before the bombers, Tinian belonged to the Chamorro world. In San Jose, the House of Taga preserves its most imposing testimony: a row of massive stone pillars, the latte, which once supported the house of a legendary chief. Only one pillar still stands, the others lie in the grass, and the site has intrigued archaeologists for generations. It's a few minutes' walk from the landing, close to the town's shops.

Tinian blue

Then there's the sea, ever present. Steps from the Chamorro pillars, the beach of the same name lines up white sand and water so clear it has given the island the expression "Tinian Blue". You swim in a sheltered cove, walk along inlets carved into the limestone, and snorkellers find coral gardens a short distance from shore. Late-day light, skimming the pale cliffs, gives the water almost unreal reflections. After the gravity of the northern airstrips, this seaside gentleness brings the day back into balance.

Port call highlights

Rarely has so much memory been concentrated in so few square kilometres. You leave with contradictory images: a concrete pit under its glass canopy, a Chamorro pillar standing for centuries, a turquoise cove where the town's children dive. Perhaps that is, deep down, what travellers on far-flung routes come looking for: places that can't be summed up.
