The present condition of the gate at the foot of its east main post, southwest sub-post and the connection beam between them was investigated mainly. Visual inspection, measuring of moisture content and drill resistance using Resistgraph as well as identification of fungi were executed. The surface layer of the posts has shown physical and biological degradation, but the results of drill resistance up to a depth of 300 mm has shown that there is no serious inner cavity associated to decay. On the other hand, it was found that an area of inner decay exists in the contact zone between the main post and the connection beam.}, pages = {157--171}, title = {〔報告〕厳島神社大鳥居の生物劣化調査}, year = {2011} }
