was inhabited by peasants and cathedral servants, around which the hamlet was huddled. Between the years 1090 and 1100, as was the case in other cities of the kingdom itself, and in the neighboring Christian kingdoms, there was an intense repopulation movement. In the eastern part of the plateau where the old Roman enclave was based stands the Burgo de San Cernin (in Spanish, Burgo de San Cernin), a settlement of Frankish craftsmen and merchants. Shortly after, the Population of San Nicolás arose, with a mixed population between Franks and natives. The Burgo de San Cernin always claimed greater antiquity over it. An important part of this whole process is the figure of Bishop Pedro de Roda, also known as Pedro de Anduque or Pedro de Rodez, occupying the seat of the diocese of Pamplona between 1083 and 1115. Pamplona's devotion to San Saturnino derives from the presence of this bishop who already in 1096 assisted Pope Urban II in the consecration of the Basilica of Saint-Sernin in Toulouse and donated to the Toulouse council itself the small church of Artajona under the name of that saint at that time. It will be during this episcopal mandate of Bishop Pedro in Pamplona when the repopulation of both Navarrería and the Burgo and the Population is documented. The Frankish settlers, settled since the end of the 11th century on the western plain of the existing urban nucleus around the cathedral, obtained the Fuero de Jaca from King Alfonso I the Battler in 1129, which granted them numerous privileges and rights. From the urban point of view, the plan of the Burgo de San Cernin has several aspects to consider; First of all, a clear separation between the Burgo, the Navarreria (the episcopal town) and the town of San Nicolás, as shown by programs of study by José María Lacarra, Julio Caro Baroja and Juan José Martinena. The layout of Navarrería follows the classic urban articulation on two main roads, perpendicular −the cardo and the decumanus− typical of Roman foundations. The layout of the plan of San Nicolás, for its part, is reminiscent of the well-known Aquitaine-Pyrenean towns, and even anticipates later English models. Contents It is made up of 29 chapters, rules, indicating the way in which the new Pamplona city council should govern its operation: symbols, election of mayors, mayor, municipal officials, administration of justice, tax collection, control of weights
