Read the shell from its hinge
A scallop shell is a familiar Camino de Santiago symbol, but its fan shape can make it an ambiguous direction sign. The ribs spread outward from the narrow hinge, so the shell has two obvious ends—and travelers may assume the broad, open edge points onward.
In Galicia, the convention described here is the reverse: the hinge indicates the direction of travel. The shell itself has not changed; the local way of reading its orientation has. A shell that appears to point backward by its wide edge may therefore be guiding pilgrims toward Santiago de Compostela.
Why the symbol can mislead
The scallop is associated with the pilgrimage, but it is not a naturally self-explanatory arrow. Its rays radiate from the hinge, and rotating the same shell changes which way the hinge faces. Along the Camino, the convention can differ by region, so a traveler who carries one rule from another province may read a Galician marker incorrectly.
When a marker also includes a painted arrow or other directional cue, follow that rather than trying to infer direction from the shell’s fan alone. In Galicia, the useful detail is small but memorable: look at the narrow hinge, not the broad end. A shell can seem to face away from the route while still showing the way.
