Abanto y Ciérvana-Abanto Zierbena

Abanto y Ciérvana-Abanto Zierbena is a municipality located in the province of Biscay, in the autonomous community of Basque Country, in the north of Spain.Administratively it has been separate from its neighbour Zierbena, about 5 kilometres to the north, since 1995; however, its name has never been officially shortened to Abanto due to there being a small village of that name in the Aragón region. The vast majority of the municipality's population do not reside in the tiny hamlet of Abanto but in the former mining settlement of Gallarta, nowadays a commuter town for Bilbao with motorway connection, train station and a large industrial estate.
