In the year 923, the king from Pamplona Sancho Garcés I conquered it for Christianity and, years later, the expression Kingdom of Nájera started being used, especially during the reign of García Sánchez III (1035-1054), named ‘that from Nájera’, due to the fact that the court from Navarre settled here.
From 1076 onwards, Nájera became part of Castille and the king Alfonso VI granted some priviledges to the township. In 1438, the title of “city” was given and a long and peaceful period of time initiated until the outbreak of the War of Independence, when the heritage of the town was greatly damaged. From 1833 onwards, Nálera became the administrative center and the headquarters of the district.
Currently, it is a dynamic township with a strong furniture industry. Its old town is located between the Castillo and Malpica mountains and the river Najerilla. In the Middle Ages both mountain ranges, as well as the city itself, were walled.
Its coat of arms, a bridge in between two castles, is clearly related to the Road to Santiago and explains the importance of Nájera, one of the few places where pilgrims could cross the river Najerilla. The San Fernando quarter, current natural development of the city, and its design on both sides of the pilgrimage route, still survive.
