The river is the Thu Bồn. The town stands on its north bank, near the mouth, in central Việt Nam, and it has stood there long enough to have been the port of a kingdom that no longer exists.

It is smaller than it sounds. The protected town is thirty hectares, three hundred metres by a thousand, with a further two hundred and eighty hectares held around it to keep the outside world at a distance.

None of it is a museum. The shutters open at half past six because there is business to do behind them, and the town has never stopped being a place of commerce.

Which is why the people who look after it describe Hội An as having two parts. There is the body, phần xác, which is the houses, the timber, the tiled roofs and the street plan. And there is the soul, phần hồn, which is the people living inside the heritage, the way they live, and the crafts they keep.

The body is what a visitor photographs.

This is a chronicle of the soul.

Ships came from across Asia and from Europe, and its best years ran from the late sixteenth century to the early eighteenth. Christianity entered Việt Nam through this harbour in the seventeenth century.

Foreign sailors wrote the name down as they heard it.

Six spellings of one place, by men who could not pronounce it and came anyway.

Through the nineteenth century it remained the main port of the central region, and it did so while the Nguyễn dynasty was operating a closed trade policy. A port at its most official and least open, still the busiest on the coast.

Then the river did the second thing rivers do. The harbour silted. Đà Nẵng rose. The ships went there instead, and Hội An stopped being the reason anyone sailed to this coast.

In the buffer zone around the town there are old tombs in Vietnamese, Japanese and Chinese style, which is the clearest surviving record of who lived and died here when the harbour was deep.

What happened next is the reason you can read any of this.

The money left. Nobody grew rich here again. And because nobody grew rich, nobody ever had the means to pull down a wooden house and put up something in concrete and corrugated iron.

The town was saved by failing.

Nobody designed this. The plan grew as the trade grew. Compare Vigan in the Philippines, the only South-East Asian trading port that ICOMOS considers comparable to this one, whose street plan was laid down by Spanish colonisers and could be any colonial town in the Americas.

A survey carried out between 1993 and 1995 counted what was there: eighteen community houses, fourteen pagodas and shrines, five meeting halls, nineteen cult houses, fifteen large tombs.

And here is the thing the survey found that a visitor never guesses. Most of those buildings, in the form you see them, are nineteenth century. Many of them keep earlier features from the seventeenth and the eighteenth. The pagodas are almost all nineteenth century too, although their inscriptions show they were founded two centuries before that.

Wood does not last. A timber building has to be repaired, and repaired again, and a town built entirely of timber must be mended continuously or it is gone inside a century. So houses framed in the seventeenth and eighteenth centuries were renewed in the nineteenth, using the same methods.

Which means the age of this town is not in its timber. It is in the unbroken line of people who knew how to replace it.

The covered bridge at the end of the street is the proof. It carries a pagoda on its back, it has been rebuilt many times, and nobody can tell you for certain how old it is.

A town that was mended for four hundred years was mended by somebody.

Around the thirty hectares of the protected town lies a buffer zone of two hundred and eighty hectares, managed to hold external threats at a distance. It is the only part of this story that works by keeping something out.

Then the visitors, and the honest version is more uncomfortable than the easy one.

The money visitors resent is the money that keeps the town standing. Revenue from entrance tickets is invested directly in the management, preservation and promotion of the property. The ticket is not a tax on seeing Hội An. It is what pays for Hội An to still be there.

That does not settle it. UNESCO's own requirements say that as tourism increases, a strategy to manage it within the parameters of the site will be required, and that strategies for the adverse effects of the climate are being developed. Both of those are sentences about work not yet finished, written by the body that inscribed the place.

And one line in those requirements is easy to read past, so here it is on its own.

Long-term management should aim to promote improvement in the living conditions for local residents.

Fourteen hundred heritage sites, and the official position is that the people who live inside them should be better off. That is the test this town is actually being set.

That 1997 statute is the reason the shutters in chapter one are wooden.

The entire town is State property.

At the time of the nomination, the centre responsible for all of this had a permanent staff of twenty five.

Twenty five people, eleven hundred timber buildings.

Today it is the Hội An Center for the Conservation of World Cultural Heritage, at 10B Trần Hưng Đạo Street. It reports on the condition of the heritage to UNESCO in Paris, to UNESCO Asia-Pacific in Bangkok, and to the UNESCO office in Hà Nội.

Multi-disciplinary research by Vietnamese and international scholars continues to inform how the town is conserved and explained.

None of this is a story about a building being saved. It is a story about people turning up for forty years to do paperwork, surveys, seminars and repairs, so that a stranger could walk down a street in the morning and think it had always been like that.

The former city is today three wards, Hội An, Hội An Đông and Hội An Tây, and one commune, Tân Hiệp, which is Cù Lao Chàm. Hội An no longer has a city-level government of its own.

And the protected zone of the ancient town lies entirely within Hội An ward.

That sentence matters more than any other in this chapter. The heritage was not divided. It sits whole, inside one administrative unit, with one body responsible for it.

The conservation centre's own account of the change is worth more than any outside reading of it. The substance of the heritage, they say, is unchanged. What has been adjusted is its distribution area and its management model.

In December 2025, marking twenty six years since the inscription, they put a number on what they are now responsible for: one thousand four hundred and thirty nine heritage sites, one thousand one hundred and ninety four of them inside Hội An ward.

At the same meeting, delegates asked for something specific. A dedicated legal framework for the Hội An World Heritage Area, completed soon.

Which is the real state of things. The 1997 statute that decides what colour a façade may be was written for a town that no longer exists as an administrative unit. The buildings are protected. The street plan is intact. What is unsettled is the frame around them, and the people in the last chapter are the ones asking for it.

There is an aim, in the property's own management requirements, to link the ancient town with the Cù Lao Chàm Biosphere Reserve beside it, and to build Hội An into a community integrating ecology, culture and tourism. Cù Lao Chàm is now Tân Hiệp commune, in the same former city.

UNESCO's own record still describes Hội An as being in Quảng Nam Province.

Everything written about this town is slightly out of date, including, for a while, this.

Which is the last thing worth saying about keeping. It was never a thing somebody finished. A Polish architect counted buildings in 1982. A statute fixed the colour of a wall in 1997. A resolution redrew the map in 2025. A meeting in December asked for a new legal framework. Somebody is doing it this week.

The body is what a visitor photographs.
