Oiartzun (Basque: Oiartzun, Spanish: Oyarzun) is a town and municipality located in the Basque Country, in the province of Gipuzkoa lying at the foot of the massif Aiako Harria (Peñas de Aya in Spanish).
The name traces back to Oiasso or Oiarso, a Roman town closely connected to the Arditurri mines in the massif of Aiako Harria, which contained large amounts of silver and copper. However, it has been pinpointed to the current border town of Irun, so the name may have referred to the whole area.
Geography
A river bearing the same name meanders through the meadows and neighbourhoods of this sparse municipality. That is one of its main features, it is scattered in different quarters across the valley. Elizalde lies on a prominence and it is the central nucleus of the town, with the main church San Esteban and town hall being located there. At the foot of Elizalde lies Altzibar by the Oiartzun River. Ugaldetxo developed into an urban built-up area surrounded by industrial estates near the AP-8 motorway, while the rest of the neighbourhoods have hung onto their rural and picturesque landscape to a large extent.
The town's football club, Oiartzun KE, plays at Karla Lekuona. The women's side has competed in the highest division of Spanish football, making Oiartzun one of the smallest towns in the country home to a top-flight club.
