This historical town of great strategic importance in the past lies in the Lumbier-Aoiz basin at the foot of the Sierra de Leire
, close to the confluence of the Irati and Salazar rivers.
In its compact urban centre, the hilly streets remind us of the proximity of the Pyrenees
. There are numerous traditional houses featuring coats-of-arms and semi-circular arched doorways framing carved doors. The oldest town hall in Navarre
stands on Calle Mayor, a Renaissance building from the 15th century.
To the south of the town, carved out by the erosion of the Irati river, is the Lumbier Gorge
, a vast gully inhabited by a huge colony of vultures along which the Irati, the first electric train in Spain, used to run.
