978-0-6485799-1-5 22nd IIWC International Symposium Wooden Heritage Conservation: beyond disciplines 30th September – 2nd October, 2019 Bilbao 978-0-6485799-1-5 Proceedings Editors Dr. Tanya L. Park, Australia 1 ISBN 978-0-6485799-1-5 Preface and Acknowledgements Since the ICOMOS International Wood Committee, IIWC, was established in 1975, the need for a set of conservation principles has been a continuous theme in the Committee’s ongoing discussions and activities. In a session of the of the 19th General Assembly of ICOMOS held in Delhi on 15th December 2017 the new IIWC ‘Principles for the Conservation of the Wooden Built Heritage’ were adopted as ICOMOS doctrinal text. These new ‘Principles’ replace those adopted previously in 1999. After the success of the 2018 symposium organized in York (UK), the challenge was to take a step further with the organization in the Basque country of a symposium and a course intended to amplify the effort in order to give a focus of a holistic approach to wooden heritage conservation that extends beyond structures to include together with the materiality of wood construction, its complex intangible side. Its scope included the diversity of professions involved, possible approaches and processes, from a global perspective and their adaptations to the conservation of local wooden heritage. This document is the publication, result of the papers presented at the 22nd IIWC International Symposium, held in Bilbao between September 29 and 2 October 2019, under the umbrella of the Summer Courses of the University of the Basque Country. This Symposium wouldn’t have been possible without the support, help and involvement of many people and organizations. Their invaluable help has been crucial not only to make a success of participation, both in number and in quality of international experts, but to raise awareness among local Institutions, and professionals. Thus, together with the rich scientific exchange among participants, the event has helped to connect also with locals. The event begun with a day-excursion to visit wooden heritage of Bizkaia and Araba, and specifically, the extraordinary Añana Salt Valley Cultural Landscape, and two also extraordinary wooden vaulted churches: Sta.

In this region with important forest resources and a municipal property regime that protected its communal goods, the wood builders maintained a natural dialogue with their resources and devised original and economic solutions for these unusual carpentry roofs that are developed in a very limited geographical area, of just 2000 square kilometres. Its 3 typologies (vaults, trusses and rafter/purlin) were limited to the construction of the roof structure and were the result of its ability to synthesize various cultural and economic factors. Through the presentation of 3 examples located in Orozko (Bizkaia), the structure of its wooden vaults and the intervention techniques used during the recent conservation
