It is believed that the present village of Lumbier goes back to ancient times to the communities of the Vascones mentioned by Roman geographers such as Pliny the Elder which included those known as the iluberritani, which traditionally have been associated with the village of Lumbier. Some Roman remains have been found in Lumbier and the remains of a Roman and Celtic villa have been found in the nearby municipality of Liédena. Starting from its ancient name of Ilumberri, linguists have reconstructed the development of its present forms.
In the Romance Languages: Ilumberri -> Lumberri -> Lumbier.
Regarding the etymological significance of Ilumberri, it is believed that it comes from archaic Basque. The first part seems to be the same as in place names such as Irún or Iruña, and it has been traditionally associated with the wordhiri o ili in Basque. The second part berri means 'new'; thus its etymological meaning would be similar to 'new town'. At present, Lumbier is located in the non-basque-speaking area of Navarre, so its Castilian name is the only official one, though the place-name "Irunberri" is still used. The inhabitants of Lumbier are generally erroneously referred to as "gatos" ; the correct expression is "ahorcagatos", which dates back to the Spanish War of Independence, when a number of French sympathisers from Madrid were caught trying to flee to France and they were hung here.
