Abstract

The article describes the latest achievements of dendrochronology at the Department of wood Science and Technology, Biotechnical faculty, University of Ljubljana, in cooperation with several institutions that are engaged in the study of wood as part of the cultural heritage. Dendrochronological dating usually tells us in which year the last ring on a wooden object was formed, but other known data have to be considered to interpret the results. In recent years we have worked on extending and improving the tree-ring chronologies that are necessary for dating. This resulted in the conclusion that for different parts of Slovenia and different periods we require chronologies of different tree species. The dendrochronological method enables us to date fir, larch, spruce, oak, and beech wood from the past millennium. Wood used in buildings (roofs, multi-floor structures, etc.) is usually preserved up to 500 years, older wood normally only under water or in wet soil (e.g. the foundation piles of buildings). Today, we are able to date wood from the Roman era. The dendrochronological analysis of wood from the pile dwellings at the Ljubljansko barje (Ljubljana Marsh) made it possible to create several chronologies from the period between 3800 and 2400 BC, which were later dated with an accuracy of ± 10 years with radiometric analysis.
