It starts with examples of specific features of surface survey of historical timber structures, mainly technological traces from historical carpentry tools and from historical surface treatment. It further introduces recent results concerning estimation of actual mechanical characteristics of historical built-in wood by means of small sample testing. This medium destructive method uses core drilling for compression tests and an extraction of small tension coupons for tension tests. The achieved results are compared to standard test results and correlated to other physical characteristics (density, annual rings). Comparative tests on deteriorated timber take advantage of impact methods (Pilodyn) and ultrasonics. Detailed studies have been carried out on cores of about 4 mm which are tested in a special fixture enabling loading the core cylinder on two opposite parallel lines as in the case of splitting te" .
