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.
