Areatza is a town and municipality in the province of Biscay, within the autonomous community of the Basque Country in northern Spain. It is one of the municipalities that make up the historical territory of Biscay, a province known for its distinct Basque cultural and linguistic heritage.
The town is situated in the northern part of the Iberian Peninsula, in a region characterised by a green, hilly landscape between the Cantabrian coast and the inland mountains. Like other settlements in the area, it forms part of the broader network of small municipalities that make up the Basque Country's administrative structure.
Areatza is officially recognised as both a town and a municipality, meaning it has its own local governing body within the Spanish administrative system. Its location in Biscay places it within one of Spain's most culturally distinctive regions, where the Basque language and traditions remain an important part of local identity.
