From the air, the tulou of southwestern Fujian look like a printing error: perfect circles and squares scattered across forested valleys, some the size of a city block. Up close they are even stranger. Each one is a single rammed-earth building, three or four stories high, with walls up to two meters thick and only one door — and until recently, most of them housed an entire extended family, sometimes several hundred people, under one roof.
In 2008, at the 32nd session of the World Heritage Committee in Quebec City, 46 of these buildings — grouped into six clusters plus four individual structures across Yongding, Nanjing, and Hua'an counties — were jointly inscribed as a UNESCO World Heritage Site under the name Fujian Tulou. More than 3,000 tulou of various forms survive across the region. This is the story of why they were built, how they work, and what it is like to walk into one today.
Who Built the Tulou, and Why
The tulou are the work of Hakka communities, a Han Chinese subgroup whose ancestors migrated south from the Central Plains over centuries of war and famine, settling in the border country of Fujian, Guangdong, and Jiangxi by the Southern Song period, roughly seven hundred years ago. As newcomers in unfamiliar hill country, they had two problems to solve at once: how to live together as a lineage, and how to stay safe while doing it.
Their answer was a building that is simultaneously a fortress, an apartment block, and a temple to the family line. Construction began in the Song and Yuan dynasties and flourished through the Ming and Qing, with the largest structures consuming the labor and savings of multiple generations of a single clan.
The Engineering: Dirt, Bamboo, and Almost No Nails
Tulou were built from what the mountains provided. Mountain loam was mixed with bamboo strips, glutinous rice paste, and sandstone, then rammed layer by layer into walls up to two meters thick. Twigs were blended into the earth to give the wall flexibility in earthquakes — a sensible precaution in a seismic region. The base sat on cobblestones for stability and moisture control, and the interior timber frames were assembled from Chinese fir with mortise-and-tenon joinery, using almost no iron nails at all.
The forms follow feng shui conventions as well as defensive logic. Circular buildings symbolize the roundness of heaven; square buildings the squareness of earth. Circular tulou had a practical advantage too — no blind corners, and better resistance to wind and tremors than square ones.
Circulation inside is strictly organized. The ground floor held kitchens, the second floor stored grain, and the upper floors were living quarters. Every building has a single heavy main gate; the first and second floors have no outward-facing windows, only narrow observation slits higher up, with watchtowers on the roof. Wells and the ancestral hall sit in the central courtyard. Sealed, a large tulou could hold out — and live self-sufficiently — for a long stretch of time.
Living Inside: One Building, One Clan
The social design is as deliberate as the structure. Rooms of equal size were allocated to branch families, so that a hundred-plus relatives lived side by side on the same terms. Weddings, funerals, festivals, and clan meetings were held in the ancestral hall at the center, following Confucian ritual that encoded the order between elders and juniors.
That is what convinced UNESCO's expert bodies: not just structural ingenuity but the fact that the tulou are the historical witness of a lineage-based, communal way of living, and a unique achievement in large-scale rammed-earth construction.
Notably, they are still lived in. Cooking smoke rises from the same courtyards in the morning, elders still dry tea and make Hakka snacks by hand, and many tulou are home to the descendants of the people who built them. They are living heritage, not abandoned monuments — which shapes how visitors should behave in them.
Which Tulou to See
Tianluokeng cluster (Nanjing county). The most photographed: four circular buildings around a square one, nicknamed "four dishes and one soup." The classic view is from the hillside above, and it is worth the climb.
Chengqi Lou, Hongkeng cluster (Yongding). Known as the "king of tulou" for its scale and its concentric internal rings — four rings inside one outer wall, with the ancestral hall at the center.
Yuchang Lou (Nanjing county). Celebrated for its wooden support pillars, which lean visibly and have stood for centuries.
Chuxi cluster (Yongding). A quieter, more village-like group with a river running through — good if you want to walk without a crowd.
Hekeng cluster (Nanjing county). The densest concentration of surviving forms, including square and rectangular buildings.
How to Visit Well
- Getting there. Most travelers approach from Xiamen, a drive of roughly two to four hours depending on the cluster; Yongding and Nanjing also have coach connections and high-speed rail to nearby towns. A full day is the realistic minimum for one cluster, two to three days to see Yongding and Nanjing properly.
- Stay a night if you can. The buildings change character after the tour buses leave, and a handful of family-run guesthouses inside the villages make that possible.
- Remember people live here. Ask before photographing residents, respect closed doors and roped-off areas, and buy tea or snacks from the families who sell them — it is the most direct way for tourism to be worth their while.
- Hire a local guide for one building. The architectural details that matter — the leaning pillars, the grain floors, the placement of the ancestral hall — are almost invisible without explanation.
- Bring layers and shoes for mud. This is a humid, misty hill region; mornings can be cool and paths uneven.
Frequently Asked Questions
What exactly is a tulou?
A large communal dwelling built from rammed earth by Hakka and neighboring Minnan communities in southwestern Fujian, typically circular or square, three to four stories high, with a single entrance and a central courtyard.
How many tulou are there?
More than 3,000 survive in various styles. Of those, 46 buildings across six clusters and four standalone structures were inscribed as a World Heritage Site in 2008.
Were they built for defense or for family life?
Both, inseparably. The thick walls, single gate, and windowless lower floors were defensive; the equal room allocations, ancestral hall, and shared wells were social.
Are the tulou still inhabited?
Many are, by the descendants of the original builder families. That is what makes them unusual among Chinese heritage sites — and why courteous visiting matters.
Which county should I choose if I only have one day?
Nanjing county for Tianluokeng and Yuchang Lou if you want the classic views; Yongding for Chengqi Lou and Chuxi if you want scale and atmosphere.
Seeing Fujian with LinkedTours
The tulou work best as a slow, quiet detour rather than a checkbox stop, and they pair naturally with Xiamen's old streets and coastal food. Our tailor-made inbound itineraries can add a tulou overnight with a local guide, arrange transport from Xiamen, and time the visit around the light — and the crowds — rather than the other way around.
