This book is a revised and completed edition of the Illustrated Dictionary of Historic Load-bearing Structures from 2004. The volume represents a course support for the author's lectures presented during the Postgraduate Studies on built heritage rehabilitation, organised at Cluj-Napoca in collaboration with the Babeş-Bolyai University. The dictionary is edited in four languages (Romanian, English, Hungarian and German) on the purpose of allowing the specialists in built heritage and historic load-bearing structures to better understand the specific terms.
