Abadiño is located on the N-636 road a few kilometres to the southeast of Durango in the province of Biscay in northern Spain.

Livestock farming is practised here on the flat valley floor, and to the south the land rises to form the Urkiola mountain range.

[3] The Astola Manor House was one of the political and administrative centres of the Merindad de Durango region.

The Gederiaga Complex is on a hill overlooking the town and includes the Chapel of San Salvador.

This was an ancient "oath chapel" in which general assemblies of the authorities of Merindad de Durango valley were held; there are twelve stone seats arranged in a semicircle, and nearby is a sandstone cross in the Renaissance and Gothic style dating from 1633, part of a series of crosses in the district.
