The conservation of monument of architecture of XIX century – the Church of St. Archangel Michael in Sevastopol is discussed in the article. The analysis of the results of the survey of the building is developed and recommendations to strengthen the supporting structures of the church are worked out. The use of traditional methods for enhancing structural and seismic reinforcement of buildings with walls of masonry leads to the inevitable loss of the original facade or interior of the temple. To enhance the analysis and design of earthquake resistant walls pasted anchors performed experimental research collaboration adhesive bonding steel anchors in the stone elements from limestone Krymbalsk deposits. The proposed measures to strengthen allow performing repair and restoration work, without breaking the historical reliability of the facades. Comprehensive solutions for strengthening and ensuring of an acceptable level of safe operation in seismic areas are developed.
