Аннотация:The northern part of Siberia still keeps much wooden historical and old architect constructions that have an interest for the history of colonization this vast territory by Russians for the past centuries.. In the paper we present materials on the use of dendrochronological methods to determine the age of the wooden chapel with a bell tower in the former Komsa village (Turukhansky district, Krasnoyarsk Krai). Now it is an abandoned village in the territory of the Central-Siberian State Biosphere Reservation. Komsa settlement has been known since 1764. Six cross sections of logs were taken from different part of the chapel for dating. Four of the cross sections have been taken from the lower rims of the chapel and two cross sections taken from the ceiling of the roof. The logs were made of trunks of Siberian pine (Pinus sibirica DouTor.). The tree-ring width (TRW) on the cross sections was measured along the longest radii on the installation LINTAB (software package TSAP). Six measured radii were from the cross sections of the lower rims, and four radii were from the cross sections of the roof. The length of the TRW chronologies varied from 125 to 265 years. All chapel's chronologies were cross-dated each other (multiple correlation coefficient 0.87). For the processing of the chronologies used a software package The Dendrochronology Program Library (DPL) (free access). The program COFECHA was used for cross dating of TRW chronologies and the program ARSTAN was used to develop of generalized chronology (DPL package). Previously obtained for this area the regional master chronology with duration 286 years (1720-2006) was used for cross dating of tested chapel's TRW chronologies. The dating showed that the chronologies of the chapel belong to the period 1638-1930. We believe that the chapel was built no earlier than 1910. Age of logs from the lower rims and one of logs of the roof ceiling refers to the period 1638-1910. The second log of the roof refers to the period 1805-1930. This may indicate that the chapel was completed (or has varied the roof element) in 1930. It can be assumed that the roof of the chapel was not completed because of the events of 1914-1917 (the First World War and Russian revolutions 1917) and the Civil war of 1918-1920. According to surviving documents of the archive in Turukhansk Museum the chapel was converted into a reading room in 1931. The external design and internal decoration of the chapel, using as construction material logs of Siberian pine, all of these is of interest to researchers of wooden architecture, as an object very well preserved, and might still serve as a historical science.
