 The "comarca" of Trasmiera was a cradle for prestigious bellfounders, whose fame transcended the Spanish borders, which granted them works in some part of Europe and America.They reached such significance that many specialists remark that there is no cathedral, basilica or church that hasn't had in its belfries some work of a Cantabrian bellmaker.In Trasmiera the job was carried out basically in the Seven Villas Assembly (made up of the villages of Ajo, Arnuero, Bareyo, Castillo Siete Villas, Güemes, Isla, Meruelo, Noja and Soano) where bellmaking workshops abounded then.
