The pilgrim arrives tired. Foncebadón is behind them and they are moving across one of the highest points of the Camino Francés, at around 1,500 metres. Ahead rises a long wooden post crowned by a small iron cross. At its foot, an irregular mountain formed of thousands upon thousands of stones.
They stop. They open the rucksack and look for a stone they may have carried from home. Perhaps it has a name written on it, a date or a word. Perhaps it has nothing. They hold it in their hand for a few seconds and then set it down on the pile. Some pilgrims pray; others keep silence. There are those who think of someone absent, those who remember something they want to leave behind, and those who simply repeat a gesture they have seen others make. Then they walk on.
The scene repeats every day at the Cruz de Ferro, one of the most recognisable places on the Camino de Santiago. But behind that apparently simple gesture lies a question that is difficult to answer: who placed the first cross there, and when did travellers begin leaving stones at its foot?
A marker in the mountains
The Cruz de Ferro stands between Foncebadón and Manjarín, in the area of Monte Irago, in the province of León. Anyone walking toward Santiago comes upon it a little more than two kilometres after Foncebadón. Today it is an obligatory stop for those following the Camino Francés, ever since its great promoter, Elías Valiña, included it in his celebrated Caminos a Compostela. Guía in 1971.
But for centuries this pass was far more than a pilgrims’ road. Muleteers, traders, harvesters and inhabitants of the nearby valleys moved through it. It was a natural crossroads between the lands of the Maragatería and the roads descending toward El Bierzo. And crossing it was risky: snow, fog and storms could erase the paths and turn the pass into a dangerous place.
Perhaps that is why the piles of stones had, from very early on, a function that was not solely symbolic. A cairn of sufficient size could serve as a marker in the landscape. Centuries later, local documents still speak of atalayas — watch-markers — that villagers maintained to indicate the road during the winters.
But much older accounts also grew up around those stones. One of the most frequently repeated explanations links the pile at the Cruz de Ferro to ancient pagan customs. In numerous places around the world, travellers have deposited stones at crossroads, mountain passes or places considered special.
Another tradition speaks even of a Roman altar dedicated to Mercury, protector of travellers and of roads. According to this interpretation, those crossing the pass left stones or offerings before continuing their journey.
There is also an explanation connecting the stones with the construction of the cathedral of Santiago. According to a popular version, pilgrims are said to have carried stones to contribute to the Compostelan works. The medieval Liber peregrinationis does indeed mention a custom of this kind, but places it between Triacastela and Castañeda, many kilometres further on.
A hermit on the Camino
Among all the stories about the monument’s origin, however, none has enjoyed greater fortune than that of the hermit Gaucelmo.
Gaucelmo was a real figure. The documentation places him in the area around Foncebadón around 1102 and connects him with assistance to pilgrims and travellers. At that time there existed in the area an infrastructure of hospitality intended to help those crossing this difficult mountain pass.
Tradition holds that it was he who placed a cross on the ancient pile of stones. The image is a powerful one. A hermit who knows the dangers of the mountain raises a cross over a cairn that travellers may already have been using as a reference point. The cross thus fulfils a double function: it turns the place into a Christian symbol and, at the same time, offers a visible marker to those advancing through snow and fog.
For a long time this story was repeated as the explanation for the origin of the Cruz de Ferro, although no document from the eleventh or twelfth centuries has been found stating that the hermit personally raised a cross at that spot.
Something similar applies to the most famous medieval document connected with the pilgrimage to Santiago. The Codex Calixtinus, compiled in the first half of the twelfth century, knows this stretch of the Camino perfectly well. Its Book V mentions the portus montis Iraci, the pass of Monte Irago, but mentions no cross.
From legend to History
The cross is nonetheless old. The first mention appears in several seventeenth-century works, where it figures as a point already known to those travelling through those lands. A map by Tomás López from 1786 includes “La Cruz de Ferro.” In 1799, a parish register records the death of a man caught by bad weather beside the “Cruz de fierro.” In the mid-nineteenth century, the geographer Pascual Madoz describes an iron cross set on a tall beam, driven into an enormous pile of stones that travellers continued to make grow.
On 5 May 1912, a cross was solemnly blessed which, according to the record preserved in the Diocesan Archive of Astorga, was to “be returned to its customary place.”
The image pilgrims know today belongs, moreover, largely to the twentieth century. In 1976 a replica of the cross and a new mast were installed, while the previous piece, presumed to be from the fifteenth century, was moved to the Museo de los Caminos in Astorga. In 1982 a small chapel dedicated to Saint James was built beside the site. In parallel, Elías Valiña’s guides and the contemporary revival of the Camino transformed that ancient mountain landmark into one of the great international symbols of the route.
And yet, after so many changes, the essential gesture remains surprisingly simple. A pilgrim arrives and leaves a stone. For some it is a prayer. For others, a memory. It may stand for a worry, a bereavement, a gratitude, an illness, a promise or a chapter of life one wishes to close. There are those who have carried their stone from thousands of kilometres away and those who picked it up that same morning beside the path.
We do not know who deposited the first stone. Nor do we know with certainty who raised the first cross. The iron has been replaced, the wood has changed and the stories have piled one on top of another.
That is why the Cruz de Ferro is far more than what meets the eye. Beneath that small cross there accumulate not only stones, but centuries of roads, accounts and anonymous lives. And every pilgrim who stops there for a few moments adds something of their own to a story that began long before them and that will probably continue long after they have gone on their way toward Santiago.
