Abstract—Reconstructing the evolution of the geomagnetic field in the European part of Russia has been an extremely challenging problem due to the still limited data meeting the up-to-date quality criteria. The paper presents the results of archaeomagnetic studies for five groups of fragments of baked clay bricks from architectural monuments of the 18th to 19th centuries in the Yaroslavl region. Paleointensity of the samples was determined by the Triaxe method involving a series of continuous high-temperature measurements. The paleointensity determinations satisfying the up-to-date quality criteria are obtained from 71 samples of 19 fragments of five archaeomagnetic groups. The obtained paleointensity data are compared with the existing data for the European part of Russia and regional reference curves for Western and Eastern Europe.
