Berezov is a city with a rich history. A significant amount of wood has been preserved on the territory of the Berezovskoe gorodishe archaeological site. For its dating, the dendrochronological method was used, which makes possible to establish the time of construction of archaeological sites (wood harvesting) with an accuracy of up to a year/season. The material for dendrochronological studies carried out at the Siberian Dendrochronological Laboratory was 190 samples of archaeological wood in the form of saw cuts. Cross-dating was carried out according to the standard method. As a result of the study, dendrochronological dating of the archaeological sites of the Berezovsky settlement (Berezovo, Khanty-Mansi Autonomous Okrug) was carried out. Twenty-six buildings from nine estates were dated. The new data made it possible to correlate the buildings with the previously identified periodization stages in the city development. Also, authors were able to take part in a discussion about the time of the city's foundation, as well as to test a new method of preparing archaeological wood samples for dendrochronological analysis.
