Irurtzun
The paths that never end
Between the Dos Hermanas (Bihaizpe) hills and the old route of the Plazaola- , Irurtzun unfolds as a place where everything finds its rhythm. Here, the routes linking Pamplona, San Sebastián and Vitoria intersect with the profound tranquillity of the beech forests surrounding the Trinidad de Erga.
This is a land marked by passage: of travellers, of stories, of seasons. The rock, firm and ancient, holds the memory. The paths, always open, invite you to continue. In that tension between transit and permanence, Irurtzun finds its way of being in the world: discreet, solid and full of nuances.
Irurtzun general information
Irurtzun is situated in the north-west of Navarre, within the Merindad of Pamplona and the Arakil Valley region. Its municipal area, covering just 3.5 km², has historically played a key role as a connecting point between the Pamplona basin and the territories to the north and west.
Over time, this strategic position made it the scene of significant events. Among these, the 1512 battle at the Ozkia Pass stands out, in the context of the conquest of Navarre, as do the clashes during the War of the Convention in 1794. Today, it retains its identity as an independent municipality, consolidated during the industrial and railway development of the 20th century.
