The alternative routes to the official Road to Santiago acquired importance in Guipuzcoa from the 14th century, thanks to the establishment of villages and to the pilgrims walking across the region on their way to Santiago.  Nowadays, it is possible to find testaments to corroborate the importance of the saint in Debagoiena during that time, one of them being the altarpiece of Santiago found in the church la Asuncion in Elgeta.

The altarpiece is located in the transept, next to the sacristy, and was crafted by Miguel Llorente in 1564.  It is not very large but it stands out especially for its height and slenderness.

Pediments and classical columns are repeated throughout the structure in the Mannerism art style fashionable towards the end of the 16th century. The most important feature is placed on the first level of the side panel: the image of Saint James carrying a pilgrim’s staff.
