Cenarruza-Puebla de Bolívar or Cenarruza-Bolívar (in Euskera Ziortza-Bolibar) is a municipality in the province of Biscay, Basque Country (Spain), in the comarca of Lea-Artibai. It has 383 inhabitants according to the 2006 census, and has an area of 18.94 km².
The name Bolibar comes from the Basque language, meaning "windmill valley" (bolu = "windmill" and ibar = "valley"), while Cenarruza possibly comes from Tzea Urriak (Cea Urriac), the Basque name of a plant very abundant in the region, or Tzear Otza, which means "cold slope".
From 1969 to 2004 it belonged, along with the neighbourhood of Cenarruza (Ziortza in Basque) to the municipality of Markina-Xemein, until a community movement managed to merge both neighbourhoods into an independent municipality.
The last name Bolívar has its origins in this locality; Simón Bolívar de la Rementería, a colonist born in this neighbourhood, took it from Europe to America, where his famous descendant Simón Bolívar, one of the Liberators of America made it famous around the world. There are a couple of statues and a museum in his honour; there was a family house in Rementería, behind the local church, but it does not exist anymore.
Other illustrious people from this small village are: Diego de Irusta, who participated in the Battle of las Navas de Tolosa; the abbots of the Collegiate church of Cenarruza; Diego and Bernardino de Irusta; the general Francisco de Longa, hero of the Spanish Independence War; and the general Pedro de Zubiaur.
The Collegiate Church de Cenarruza or Ziortza is located at roughly two kilometers from the urban nucleus. It was an important enclave in the Route of Santiago de Compostela, and its influence extended beyond the comarca and surpassed the religious scope.
Tradition marks its founding in the 10th century with a legend, according to which on the day of the Assumption of the year 968 the local inhabitants held a mass in the Church of Santa Lucia de Garay, when an eagle picked up a skull from an opened tomb and dropped it in the place where the Collegiate Church is situated today. The people understood this event to be a sign and raised the religious complex in that place.
The complex consists of:
There was a hospital for pilgrims that was destroyed in a fire and was subsequently rebuilt as a hostel managed by Cirtercian monks and property of the monastery of Oliva in Navarra. There are remains of a walkway which formed part of the Santiago Route.
