    PETROLEOS DEL NORTE, S.A. (PETRONOR) was founded in Bilbao in 1968 with the corporate purpose of refining and marketing oil and oil-related products.

    After a number of changes to its shareholder structure, the current partners in the company are: REPSOL, S.A (85.98%) and BILBAO BIZKAIA KUTXA - BBK (14.02%).

    Petronor is Spainís largest refinery, with a processing capacity of eleven million tons a year. The firmís premises are located in the districts of Muskiz, Abanto and Zierbana and are linked by oil pipelines to the docking facilities at Punta Lucero five kilometres away, to the nearby CLH terminal (which provides the company with its connection to the Spanish pipeline network) and to a number of local companies.

    The Company logo shows the battlements of the 15th-century castle tower of Muñatones, located on the edge of the refinery. The castle, like the Palace of the Salazar family, now the Company headquarters, is part of Spainís national artistic and historic heritage.
