Festival of o Percebe de Aguiño Activity · Ribeira, Barbanza, A Coruña Image of Ribeira, not of the place itself. A festival organised since 1997 by the fishermen's guild of Aguiño around the goose barnacle torn from the wave-beaten rocks of the coast, a shellfish whose gathering is shared out by turns and quotas among the percebeiros.
