The Camino shell and the yellow arrow: what they mean and which way they point

Two signs take you all the way to Santiago. The scallop shell has marked pilgrims since the Middle Ages and tells you that you are on the Camino. The yellow arrow dates from the 1980s and tells you where to turn. Only one of them works as a compass, and it is not the famous one.

Why a scallop shell?

The scallop, vieira in Galician and Spanish, is the shell of the Galician coast, and medieval pilgrims carried one home as proof that they had reached Santiago. The Codex Calixtinus, the 12th century book of the pilgrimage, already mentions it, and the oldest known image of it as the pilgrims’ badge, a carving at Santa Marta de Tera in Zamora, is from about 1125. Shells could only be sold in Santiago, and the street where the sellers worked, where the Camino Francés enters the city, is still called Os Concheiros. It was useful too: you could drink from it.

The legend of the rider

A legend tells it differently. As the boat carrying the body of Saint James came in to the Galician shore, a wedding was taking place on the beach. The groom’s horse took fright and plunged into the sea with him, and horse and rider came out of the water alive, covered in scallop shells.

Who painted the yellow arrows?

Elías Valiña (1929 to 1989), the parish priest of O Cebreiro. In 1984, the Galician government says, he marked the whole Camino Francés himself, from Roncesvalles to Santiago, with yellow paint left over from painting signs on the N-VI road. The colour was chance, not a plan. Some accounts date his first arrows earlier, to 1980. Valiña also directed a pilgrim’s guide for Spain’s tourism office in 1982 and helped found most of the Spanish Camino associations, whose volunteers still repaint the arrows. The other routes took up his arrows, which is why you now follow them all over Spain and Portugal.

The blue tile with the yellow shell

In 1987 the Council of Europe made the pilgrim routes to Santiago its first European Cultural Route and gave them an official sign: a stylised yellow scallop shell on a blue ground. Its lines meet at one point, like the routes from all over Europe meeting in Santiago. That is the shell on the tiles and bollards you walk past today.

Which way does the shell point?

There is no single rule. Some guides say the wide end of the shell shows the way in Galicia and the narrow end everywhere else; others read it the other way round. A specialist guide says the placement varies by region and advises not to steer by the shell at all, only to take it as proof that you are still on the route. We found no official rule that settles it. The yellow arrow has no such problem: it always points towards Santiago.

The Galician bollards

In Galicia the waymarks become granite bollards, mojones: the shell on a blue tile, a yellow arrow and a plate with the distance left to Santiago. On the bollard, read the arrow.

Wearing the shell

Medieval pilgrims brought a shell home at the end. Today many tie one to their rucksack on the first day. It marks you as a pilgrim, which is what it has always done.

The shell says you are a pilgrim; the credencial proves it, one stamp at a time.

The bollards count down the last 100 km.

Valiña’s church still stands at the top of the climb into Galicia: O Cebreiro.

The other thing you will meet at every junction is a greeting: what Buen Camino means.

And the medieval one: what Ultreia means.
