Abanto y Ciérvana-Abanto Zierbena

Administratively, it has been separate from its neighbour Zierbena, about 5 kilometres (3.1 mi) 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 does 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 (Autovía A-8), train station (Cercanías Bilbao C2 line) and a large industrial estate.
