Proceedings of the 3rd International Conference on Architecture: Heritage, Traditions and Innovations (AHTI 2021)

The present thematic collection of scientific articles is the result of the 3rd International Conference on Architecture: Heritage, Traditions and Innovations (AHTI 2021) held in Moscow on March 9–10, 2021. Due to the COVID-19 pandemic, the conference was held online, on the Zoom platform.

The first conference under the same title, which took place in February 2019, was followed by the publication of a similar collection of articles — the Proceedings of the 2019 International Conference on Architecture: Heritage, Traditions and Innovations (AHTI 2019). The next conference held in February 2020, was followed by the publication of the Proceedings of the 2nd International Conference on Architecture: Heritage, Traditions and Innovations (AHTI 2020).

AHTI 2021 was organized by the Scientific Research Institute of the Theory and History of Architecture and Urban Planning (NIITIAG) (Russia) and was participated by the Russian Academy of Architecture and Constructive Sciences (Russia), the State Institute for Art Studies (Russia), the André Chastel research Centre in History of Art of the Sorbonne University (France), the Institute of Arts of the National Academy of Sciences of the Republic of Armenia (Armenia), the Faculty of Architecture of the Belarusian National Technical University (Belarus), the International Science and Culture Center for Academic Contacts (Russia), and Zhengzhou Yingchun Conference planning Co., Ltd., (China).

In 2021, the 3rd International Conference on Architecture: Heritage, Traditions and Innovations attracted scholars from nine countries (Russia, France, Italy, China, Ukraine, Belarus, Armenia, Kazakhstan, and Syria). The scientific scope of the conference and the importance of topics discussed in conference sessions became the reason for the representatives of universities and research institutes to take interest in the 3rd conference.

The conference abstracts are traditionally published on the official webpage of the Scientific Research Institute of the Theory and History of Architecture and Urban Planning:
http://www.niitiag.ru/events/past/architecture_heritage_traditions_and_innovations_2021
and one of the leading Russian digital platforms on architecture – Archi.ru : https://archi.ru/lib/book.html?id=2146113768&fl=5&sl=5

AHTI 2021 is devoted to a wide range of problems of the history and theory of architecture and concentrates on the correlations between heritage preservation and contemporary architecture, between traditional and innovative approaches to its development. The conference organizers tried to bring together scientists from different countries on a joint discussion platform in order to link their ideas on the innovative development of architectural creativity and the traditional ideas reflected in the centuries-old architectural heritage, to identify the ways to solve one of the most pressing issues of our time — the balance between rapid expansion of architectural and urban planning activities, and the need to preserve architectural monuments and valuable historical environment. At the plenary session of the conference and its thematic sessions entitled "History and theory of architecture: from the ancient times to the early modern period," "History and theory of architecture: from the World War I to the contemporary times," "Architectural heritage protection and contemporary use," "Innovations in contemporary architecture," and "Architectural aspects of town planning", the conference participants discussed the issues of architectural heritage preservation and systematization, the development of architectural schools, the interaction of architectural traditions, peculiarities of architectural creativity, the formation of innovative concepts, architectural ideas, and their implementation.

The 3rd International Conference on Architecture: Heritage, Traditions and Innovations was participated by 120 scholars, and 63 articles were accepted by our reviewers. All papers included in this collection underwent careful review by three experts before being selected for publication. Strict submission criteria for the previous volume of the AHTI series became the reason for the increased interest of our colleagues in the 3rd conference.

The Proceedings include the following chapters: "History and theory of architecture: from the ancient times to the early modern period", "History and theory of architecture: from the World War I to the contemporary times", "Architectural heritage protection and contemporary use", "Innovations in contemporary architecture" and "Architectural aspects of town planning".

The chapter entitled "History and theory of architecture: from the ancient times to the early modern period" includes articles devoted to the understudied aspects of the architecture history and introduces new, previously unknown data on monuments of world architecture. Furthermore, the articles of this chapter clarify the attribution of a number of buildings and reveal the connections and mutual creative influences of a number of regional and national architectural schools.

The chapter "History and theory of architecture: from the World War I to the contemporary times" includes articles devoted to several questions of the history of architecture of the last hundred years - the period of large-scale construction and architectural development. This chapter reveals the processes of global and regional development of architecture and its most important and less studied evidences and works.

The chapter "Architectural heritage protection and contemporary use" discusses the theory and practice of historical and architectural heritage preservation, including its legal aspects and issues related to contemporary use and architectural and structural renovation. The issue of historic cities and the preservation of their historical, architectural and urban-planning identity have also been taken into consideration in this chapter.

The chapter "Innovations in contemporary architecture" reflects the phenomena and processes caused by the transformations in the modern cultural space in the sphere of architecture and urban planning, and discusses new opportunities in architecture provided by digital technologies. The main emphasis is on the new types and forms of architectural and artistic expression, and methods of formation.

The chapter "Architectural aspects of town planning" comprises articles devoted to the theory and practice of modern architecture and urban planning, and problems and prospects of their development.

We hope that AHTI 2021 Proceedings will contribute to the development of fundamental science in the fields of architecture, urban planning, heritage preservation, and art criticism, and that the ideas expressed in the articles will elicit response in contemporary architectural and urban planning practice and architectural creative work.

We would like to thank the organizers and the members of the scientific committee. Especially, we would like to express our gratitude to the reviewers who worked very hard to review the papers and suggest improvements, and the authors for contributing their research results to the conference.
