Duong Lam, the village built out of laterite
On this page
Duong Lam is a village made of the ground it stands on. Laterite, cut in blocks and stacked into walls the colour of dried blood, an hour west of Hanoi.
What is laterite, and why is the village built from it?
Laterite is a soft, iron-rich soil that hardens permanently once it is cut out and exposed to air. This part of the Red River delta sits on it, so builders quarried blocks locally, laid them without mortar and let the weather set them.
The result is a village of walls in every shade from ochre to rust, pitted like coral and warm to the touch. Nothing else in Vietnam is built this way at this scale. That is why the whole settlement, rather than a single building, carries national heritage status.
What should you actually look at?
The Mong Phu communal house at the centre is the anchor. It is a seventeenth-century dinh on a raised platform, open on all sides, and still the meeting place of the village. From there the lanes run outwards between laterite walls too narrow for two cars.
Several old family houses open to visitors, marked at the gate. The best of them are working farmhouses with a beaten-earth yard and a hundred glazed jars in it. Two of Vietnam's early kings, Phung Hung and Ngo Quyen, were born here, and each has a temple at the edge of the village.
| What | Time | Notes |
|---|---|---|
| Mong Phu communal house | Half an hour | 17th century, open sides, village centre |
| The laterite lanes | An hour | Best in early or late light |
| Open family houses | An hour | Marked at the gate, buy something |
| Ngo Quyen temple | Half an hour | On the edge, quiet, walkable |
| Soy sauce yards | Twenty minutes | Jars in rows, sold by the litre |
How old are the houses?
The oldest open to visitors date from the seventeenth century, and several carry a beam inscribed with the year they were raised. Around 900 houses in the village group are built of laterite, and a few hundred of those are counted as old in the heritage listing.
Age here means continuous use rather than preservation. A four-hundred-year-old house has a television in it, a motorbike in the yard and a new tin roof over the back kitchen, which is what separates Duong Lam from a restored site.
Why are there jars in every courtyard?
Because Duong Lam makes tuong, the fermented soybean sauce that northern cooking uses where the south reaches for fish sauce. Soybeans and glutinous rice go into glazed jars. The jars stand open to the sun for months, stirred with a wooden paddle every few days.
You can buy it by the litre at the house that made it. Tuong tastes nothing like Japanese or Chinese soy: thicker, sweeter, grainier. It is what a northern kitchen dresses boiled greens and braised fish with.
Is it a tourist village?
Not yet, and that is a matter of degree rather than principle. A ticket booth at the entrance charges 20,000 dong. A handful of houses take visitors, and a few families sell tuong, sweets and tea.
Everything else is farming. Drying racks take up half the lanes at harvest and dogs own the shade. The families in these houses did not sign up to be looked at, so ask before stepping through a gate; the etiquette guide covers the rest.
How does it compare with Hoi An or Bat Trang?
Hoi An is a preserved trading town with a tourist economy built on it; Duong Lam is a working village that happens to be old. Bat Trang, the pottery village on the other side of Hanoi, sits between the two — a real trade with a market attached.
The comparison that matters is the one with your own time. Duong Lam gives you two quiet hours and no shopping, and the craft villages guide covers the places that give you the opposite.
What else is on the same road?
Ba Vi is about 20 km further west, and the two together are the best day west of Hanoi. The village in the morning while the light is low, the mountain and its French ruins after lunch.
Son Tay, 4 km before the village, has a laterite citadel of its own from 1822 and a market worth twenty minutes. The Hanoi day trips page ranks this direction against the others.
FAQ
What is Duong Lam?
Duong Lam is a cluster of villages 44 km west of Hanoi, built almost entirely from laterite, the red iron-rich stone cut out of the ground here. Several hundred houses survive, some of them three and four centuries old, and people still live in them.
How do you get to Duong Lam from Hanoi?
About 44 km and an hour to an hour and a half by road, past Son Tay. Buses run to Son Tay from My Dinh and leave a short taxi or xe om ride at the end, and most visitors come by car or motorbike.
What is there to see in Duong Lam?
The Mong Phu communal house at the centre, the laterite lanes around it, several old family houses that open to visitors, the temples of two kings born here, and the soy sauce jars standing in the courtyards.
Is Duong Lam a museum or a real village?
A real village, which is the point and also the etiquette problem. People live and farm in these houses, they are not staffed sites, and the families that open their doors do so on their own terms and appreciate being asked.
How long do you need at Duong Lam?
Two to three hours covers the lanes, the communal house and two or three of the open houses at an unhurried pace. It works best as a half day paired with somewhere else on the same road west.
When is the best time to visit Duong Lam?
October to April, when the north is dry and the light is low enough to show the laterite. Go on a weekday morning: weekends bring Hanoi day-trippers and the lanes are narrow enough that a few dozen people fill them.
