 Goulven has a reliquary consisting of an arm made of wood, which contains an arm made of silver, which in turn contains a relic of the saint.Places named for the saint are found in the Breton communes of Lanvellec (St-Goulven), Caurel (St-Golven), Lanloup (St-Golven), Plouider (Keroulien), Taupont (St-Golvin), Feuillée (St- Voulc'hien), Bubry (Locolven), Inguiniel (Locolven), and Locmaria-Plouzané (Goulven).If Goulven is to be identified with the saint Gonvel or Gonval venerated in the commune of Landunvez, as seemed likely to Plaine, then 9 or 10 small chapels and altars there are also to be connected to Saint Goulven.
