The town of Antoñana was founded in the 12th century (1182) by King Sancho VI of Navarre, upon a population centre that had previously existed as a fortified site at a crossroads.
Its outstanding architectonic feature is its wall or defensive ramparts, recognisable in almost the entirety of the perimeter. .
The centre is made up of five streets going from north to south, crossed by alleys and passageways, dominated at the southern end by the Church of San Vicente.
