Understanding Cultural Heritage Conservation

The Time Honored Architectural Conservation Documentation Project

Understanding Cultural Heritage Conservation

Architectural conservation practice throughout today’s world is both pervasive and dynamic. Practically every country is involved in identifying, conserving, and celebrating its architectural heritage, and interest in the subject is growing. The Time Honored Architectural Conservation Documentation (THACD) project describes trends and accomplishments in the field and notes contributions to the profession made in different places. This series aims to gather intelligence about ideas and actions—especially solutions—in built heritage protection toward offering a basic synthesis and some conclusions.


The THACD project website supplements an emerging multi-volume series of books that offers global perspectives on architectural heritage protection practice in different parts of the world. The first book, Time Honored, A Global View of Architectural Conservation; Parameters, Theory & Evolution of an Ethos was published in 2009. Architectural Conservation in Europe and the Americas; National Experiences and Practice, which profiles building conservation practice in some 67 countries, followed it in 2011. A third volume, Architectural Conservation in Asia; National Experiences and Practice, published in 2017, similarly describes architectural heritage protection in the 27 countries of Eastern Asia. A fourth title in the series, Architectural Conservation in Australia, New Zealand, and the Pacific Islands was published in early December 2023.

​The authors—John H. Stubbs for Time Honored, John H. Stubbs and Emily G. Makaš for Architectural Conservation in Europe and the Americas, John H. Stubbs and Robert G. Thomson for Architectural Conservation in Asia, and John H. Stubbs, William R. Chapman, Julia Gatley and Ross King for Architectural Conservation in Australia, New Zealand and the Pacific Islands—based their research on their experiences in the field and in various informational sources. These research and publishing projects owe much to friends and colleagues who contributed to the writings and otherwise assisted with the effort. We sincerely thank them and our other supporters herewith. 

Though the authors have endeavored to consult all available key institutional and professional resources, we are aware that quantities of material about the field have yet to be identified. Our hope is to engage others in questioning and benefiting from a broader perspective on today’s phenomenal systems of cultural heritage conservation practice. It is for this purpose that the present research effort, aided by this website, is being shared.
