High in the Lasta mountains of northern Ethiopia, about 645 kilometres from Addis Ababa, there is a town where the churches are not built. They are carved.
Lalibela holds eleven medieval churches cut out of solid volcanic rock. UNESCO lists them as a World Heritage Site, and they were among the very first twelve places inscribed on the World Heritage List in 1978. Their creation is attributed to King Lalibela of the Zagwe dynasty, who ruled in the late twelfth and early thirteenth century. According to UNESCO, he set out to build a "New Jerusalem" after Muslim conquests had halted Christian pilgrimages to the Holy Land. Even the landscape carries the idea: a channel cut through the site is named the Yordannos, the Jordan.
Most visitors come to see one church above all. And what makes it remarkable is not only how beautiful it is. It is how it was made.
Building from the top down
Almost every building in history goes up. You lay a foundation, raise walls, and put a roof on last.
Lalibela's builders went the other way. As the Metropolitan Museum of Art describes it, workers first traced the outline of a church on the surface of the rock. Then they cut deep trenches around it, isolating a single giant block. Only then did they begin to shape it, working with chisels, axes and other blades, refining the outside and hollowing out the inside: doors, windows, columns, floors and ceilings, all from the same piece of stone.
That means the roof was finished first and the floor last. Every window, every arch, every cross was made by taking stone away.
The most famous of them, Bete Giyorgis, the Church of Saint George, shows how far the method could go. Seen from above it is a perfect cross, with three Greek crosses carved one inside another on its roof. It is about 12 metres wide and roughly 12 metres high, standing on a stepped platform at the bottom of a pit about 25 metres square. It has three doors, twelve windows and, below them, nine false windows that were carved for the look of the facade but never opened. Visitors reach it by walking down a trench and through a tunnel.
There is a legend about it, too. Local tradition says King Lalibela built it only after Saint George, Ethiopia's patron saint, reproached him for not building him a house.
No undo button
Think about what carving downward demands.
When you build with bricks, a mistake can be fixed. You knock down a wall and lay it again. When you carve a building out of a mountain, there is no putting stone back. A wrong cut on the roof stays wrong forever. A wall carved too thin cannot be thickened. The decision about where the floor would be had to be right long before anyone reached it.
So the work had to be planned before the first blow. The outline traced on the rock was not a sketch to be improved later. It was a commitment.
Historians still debate exactly how long the work took and who did it. Some scholars think the churches were carved over a longer period, possibly from the tenth to the thirteenth century or later, with some adapted from earlier structures; Bete Giyorgis itself is usually dated to the late twelfth or early thirteenth century. But whatever the timeline, the method left no room for careless work. Every stage depended on the one before it.
The part nobody photographs
There is another detail that gets less attention than the soaring walls.
Carving deep into the ground creates an obvious danger: water. Rain and groundwater could flood the pits and eat away at the stone. So, the Met notes, the builders cut drainage canals and trenches to carry water away, and the roofs of the four free-standing churches slope at the same angle as the rock they came from, which helps water run off. Other channels fed cisterns and baptismal pools. UNESCO describes an "extensive system of drainage ditches, trenches and ceremonial passages" linking the site.
None of that is what tourists come to photograph. All of it is part of why the churches are still standing more than 800 years later.
And they are not museums. Lalibela is a living place of worship. A 2018 UNESCO advisory mission counted almost 800 priests serving there, with daily services and thousands of pilgrims arriving for Ethiopian Christmas and Easter. The churches have survived because a community has kept using them, caring for them and passing on their meaning.
The lesson for enterprise and industry
A lot of modern work is more like carving than building, even if we pretend otherwise.
In a factory, a batch that has been mixed cannot be unmixed. Product that has been packed and shipped cannot be quietly corrected. A cut in steel, a contract signed, a production run started on the wrong specification: these are downward cuts. You can only take away from what you have.
Lalibela's builders teach three things about that kind of work.
Plan before the first cut. The outline on the rock was the specification, agreed before the work began. In industry, the equivalent is a clear recipe, drawing or standard that everyone works from, instead of decisions made up on the floor.
Check at every stage. You cannot carve the floor and then discover the roof is wrong. Checks have to happen while there is still something to save: at intake, during the run, before packing. Quality found at the end is just a record of what went wrong.
Build the drainage. The unglamorous systems, maintenance schedules, cleaning routines, records, backups, the people who care for the work after it is finished, are what let anything last. They never make the brochure. They are the reason there is a brochure in the second century of a company's life.
Lalibela's churches were cut from a mountain by people who knew that some mistakes cannot be reversed, so they designed their work to avoid them. Eight centuries later, people still walk down those trenches to pray.
So here is my question for every founder, manager and plant team:
Which of your processes cannot be undone, and are you checking them before the cut or after it?
