We report an archeomagnetic study from the Early Iron Age archeological site of Cerro de
San Vicente (Salamanca, Spain). The studied materials were sampled from one roundhouse and its central
fireplace, a surrounding burnt floor, and slags with a twofold objective. First, to archeomagnetically
determine 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 period
when the Levantine Iron Age Anomaly (LIAA) has been occasionally reported. This study includes
mineralogical, archeomagnetic directional analyses, and multimethod archeointensity determinations.
Paleomagnetic analyses of the central fireplace yield a mean direction: declination D = 15.1°, inclination
I = 52.5°; k = 477.1, and α95 = 5.6°. Archeointensity determinations yield a mean anisotropy-corrected
archeointensity of 72.4 ± 2.0 μT (74.7 ± 4.3 μT if a pTRM-check correction is applied) on the central
fireplace 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 between
644 and 575 BCE (654–575 BCE with the pTRM-check corrected data) at 95% confidence level. This date
agrees with the archeological context. Results allows to place the high paleointensity obtained near the
maximum observed in Iberia at this age, confirming the existence of this peak related to the LIAA in
Western Europe where records of this feature are still scarce.
