  abstract = {{A}lignments of heating stones hearths are common in {S}outheast {F}rance and in {S}witzerland at the {L}ate {B}ronze and {E}arly {I}ron {A}ges. {B}ecause of the plateau effect on the radiocarbon calibration curve, the hypothesis that the structures were in use almost synchronously within an alignment is still debated. {F}or archaeomagnetic dating purposes, we studied eight heating stones hearths, six of them organized in two parallel alignments, from the site {C}los de {R}oques - {R}oute de {B}arjols in {S}aint-{M}aximin-la-{S}ainte-{B}aume in {S}outhern {F}rance. {A}rchaeodirections were determined after thermal and alternating field demagnetizations and archaeointensities using the {T}hellier{T}hellier protocol with corrections for the anisotropy and cooling rate effects. {T}he large difference between average archaeodirections (more than 20 degrees in declination) clearly demonstrate that the last use of the structures was not contemporaneous, bearing in mind that no archaeological evidence of multiple uses was found. {T}he archaeomagnetic dates were obtained with the local prediction of declination, inclination and intensity by the {E}uropean geomagnetic model {SCHA}.{DIF}.4k. {T}hey range between the end of the 8th century {BCE} and the end of the 5th century {BCE} with a similar to 150 years precision at 95 % of confidence for most structures. {T}hese results confirm the occupation of the site at the {E}arly {I}ron {A}ge given by other dating methods but imply a longer use than the one around 625-575 {BCE} suggested by the typochronology of ceramic artefacts. {T}he different archaeomagnetic dates obtained within the alignments show that the alignments of hearths were not established over a short period as previously thought but over a couple centuries, highlighting the important and still poorly understood role of these fired structures in the area.},
