El Archivo Municipal de Pamplona se encuentra en el primer piso de la Calle Mercado número de 11 de Pamplona.
Two archive centers exist which are interested in conserving and cataloging everything related to Sanfermin. One of these is the Archivo Municipal de Pamplona (City Archives) and the other is the Archivo de la Casa de Misericordia de Pamplona (The governing body of the fiestas). Both institutions accept altruistic donations with the aim of conserving material about the fiestas and they offer a high level of professionalism in their treatment of the material as well as ensuring copyright and safekeeping.
The Archivo Municipal de Pamplona conserves the best photographic material on the fiestas and on the running of the bulls. This is especially so ever since the donations made by the inheritors of material from Zubieta y Retegui or José J. Arazuri. They also keep the best collection of posters and programs from the Sanfermin fiestas. In addition, they have plans and drawings on the chapel of the saint and a register of all the city hall activities related to the fiestas down through the years. At present, the person in charge of this material is Ana Hueso and contact may be made with the archive center here.
Perhaps the other important record office is less well known - that of the Casa de Misericordia de Pamplona, which belongs to the charitable foundation of the Old Folk's Residence and which is a charitable and non-profit-making entity. Here you can find information that goes back some 300 years and which is related mostly to the bullfights and the running of the bulls. The "Meca", as this foundation is popularly known as, organizes the running of the bulls and the program of bullfights and for that reason it keeps records such as the posters of the bullfights or the erection of the fencing, etc. Old tickets, programs, photos, etc. can all be found here in their collection. The person responsible for the historic archives is Beatriz Itoiz and contact with the archive may be made here.
