Scientific Essay from the year 2016 in the subject Art - Architecture / History of Construction, language: English, abstract: To understand the technological, aesthetical and symbolic value of the surviving timber framed walls and to plan their restoration and protection, historical documentation is needed. Archaeological finds from the 16th century BC (Thera / Greece) and the 1st century AD (Herculaneum / Italy) have provided physical evidence, and written documents of 1st century BC (Vitruv) and 17th century AD (Dela Valle) give analytic description. Allusions to these walls made up until today help us to form an idea about the development of various timber wall types, over the last three one half thousand years. The surviving buildings were generally built after the 18th century AD. Some of the main characteristics of their static system and construction will help to identify the various forms of technology, aesthetics, materials and construction procedures.
