AB We report an archeomagnetic study from the Early Iron Age archeological site of Cerro deSan Vicente (Salamanca, Spain). The studied materials were sampled from one roundhouse and its centralfireplace, a surrounding burnt floor, and slags with a twofold objective. First, to archeomagneticallydetermine the last use of the central fireplace, because dating with other methods was imprecise.Second, to retrieve information about the Earth's magnetic field in Western Europe from a periodwhen the Levantine Iron Age Anomaly (LIAA) has been occasionally reported. This study includesmineralogical, archeomagnetic directional analyses, and multimethod archeointensity determinations.Paleomagnetic analyses of the central fireplace yield a mean direction: declination D = 15.1°, inclinationI = 52.5°; k = 477.1, and α95 = 5.6°. Archeointensity determinations yield a mean anisotropy-correctedarcheointensity of 72.4 ± 2.0 μT (74.7 ± 4.3 μT if a pTRM-check correction is applied) on the centralfireplace and 48.2 ± 2.0 μT on slags. A full-vector archeomagnetic dating was performed with the SHA.DIF.4k geomagnetic field model which yielded an age interval of last use of the central fireplace between644 and 575 BCE (654–575 BCE with the pTRM-check corrected data) at 95% confidence level. This dateagrees with the archeological context. Results allows to place the high paleointensity obtained near themaximum observed in Iberia at this age, confirming the existence of this peak related to the LIAA inWestern Europe where records of this feature are still scarce.
