Zubillaga (pronounced as /es/, pronounced as /eu/) is a village and concejo located in the municipality of Lantarón, in Álava province, Basque Country, Spain.[3] It was established in the late 1940s as a neighborhood for the workers of a nearby chemical plant. It acquired its current name in 1989,[4] when it was segregated from Comunión.[5]
