introduction urban conservation is a concept that has been with us since at least the 1960s sustainable development is a concept that originated in the 1980s and has become one of the core agendas of our time although their roots are different conservation and sustainability share common ground this book sets out to examine how these issues relate to each other in the context of historic cities it aims to identify weaknesses in current philosophy and practice in urban conservation set out the relationship between successful architectural conservation and wider agendas of sustainability and cultural identity summarise the communality of approach and practice that needs to be fostered and developed between a complex range of interrelated issues and disciplines enhance both the perceived relevance of architectural conservation and its level of attainment extend the achievement of the goals of sustainability in the context of historic cities and highlight the opportunities for conservation and sustainability to work in a partnership of profound strength and mutual achievement previous publications have focused on conservation and sustainability as though they are separate issues perceptions however are changing new linkages are being forged and this book seeks to contribute to this important process the starting point for this book is the united kingdom it draws from examples of theory and practice across europe and elsewhere around the world vii

acknowledgements the origins of this book date back to two post-graduate dissertations that i prepared at university in the early-1970s one that related to edinburgh the other to countries across western europe over the intervening period the ideas and material that have gone into its preparation owe so much to so many people that it would be invidious to name them individually and risk omitting some of the most influential including many whom i have never met and know only through their work suffice it to say first that the support of colleagues contemporaries and friends in cities as diverse as london bath cambridge derby and edinburgh within the united kingdom and in cities across the length and breadth of continental east and west europe and beyond has been decisive second that my interest and perseverance in architectural and urban conservation and their relationships to modern architecture and town planning owe an enormous debt to the support of the late sir leslie martin my professor at cambridge and a noted modernist in his own professional career he had an inclusive approach to the challenges that budding architects should be prepared for in the future and supported and encouraged me at a time when the topics were even less fashionable in the generality of the schools of architecture than they are today viii

definitions conservation and sustainability the context of this book is historic cities and the theory and practice of conservation and sustainability in relation to them in the wider environmental sense conservation and sustainability have parallel meanings and are frequently used interchangeably to express the need to manage the world s natural resources and the biosphere in order first to secure long-term harmony between man and nature and second to achieve continuous enhancement in the environment and in the conditions and quality of life for humans and other life forms it is in this broad sense that sustainability is used in this book conservation on the other hand has a much narrower meaning when applied to historic cities the principal root is architectural conservation whose starting points include archaeology and the geocultural diversity and historical evolution of architectural styles building materials and techniques the secondary root of urban conservation is townscape and a morphological and aesthetic approach to the management of change in historic cities neither architectural conservation nor townscape is founded upon a preoccupation with sustainability both however have the potential to make a significant contribution to it ix

chapter 1 conservation background architectural conservation beginnings and evolution the history of modern architectural conservation has been traced to the confluence of christianity and humanism at the time of the italian renaissance and to the recognition of classical antiquity both as an important epoch of the past and a springboard for cultural continuity and creativity monuments whether ruined or otherwise became prized for their inherent architectural and visual qualities as well as for their historical and educational value in short as predominantly today for their architectural and historic interest figure 1.1 by the eighteenth century the age of reason or enlightenment in europe advances in the sciences coupled with an increasingly adventurous interest in the antiquities of greece and rome led to the development of methodologies for verifying facts from primary sources and the founding of modern archaeology and art history the concept of authenticity based on reliable information sources which is a cornerstone of modern conservation philosophy and practice is a product of that time the eighteenth century is also noted for the picturesque movement inspired by romanticised paintings and engravings depicting the landscape and ruins of antiquity and by a growing interest in the medieval period in england this movement expressed itself in the landscaped park and the protection restoration and frequent construction of replica or false ruins for their picturesque value figure 1.2 today ruins which in the united kingdom are classified separately from historic buildings as ancient monuments continue to be prized for their picturesque value and there is a presumption by some against their being brought back into human occupation and practical use the eighteenth century also saw the beginnings of custodianship and systems of protection together with the emergence of a sense of common ownership whereby important works of art and other authentic manifestations of a particular culture are seen as transcending national barriers the collections of many of the great museums and art galleries of the world date 1
