Heritage stones are those stones that have been used for many years, even centuries, to build the historic buildings and monuments of places around the world. Some of these stones are still being used for construction, but others are no longer used, either because quarries were exhausted or closed or because architects and constructors do not know about their particularities and importance. Several scientific papers discuss many of these stones, and a number of papers are currently being prepared, but this book is the first to emphasize the importance and significance of natural stone in the construction of a city, Salamanca, recognized as a World Heritage Site by UNESCO since 1988. In light of this recognition, Salamanca has a duty to preserve all historic buildings that make up the city by restoring those that are starting to deteriorate centuries after their construction. This book describes the buildings, the stones (all quarried centuries ago in the surrounding area), and the stone quarries, some of them inactive for many years, but that should still allow extraction of blocks on demand to restore and replace damaged specimens in the buildings, preserving the very character that saw the city receive recognition by UNESCO in the first place. There are many other places around the world that should follow this initiative and disseminate the importance of their heritage stones. This book will be of interest to professionals and academics in Geology, Engineering, architectural and artistic work in stone, both construction and conservation, but also to the general public.

Apulian limestones constitute the historic building constructions of the Puglia region (in the south of Italy) named trulli (representing an outstanding universal value for UNESCO), but also other stone buildings of the well-known Itria Valley. Trulli are drywall (mortarless) constructions made of roughly worked limestone blocks collected from neighbouring fields. The limestone for trulli is quarried from different Apulian localities and, together with another local lithotype, represents the stone heritage of the Itria Valley. This book begins with an introduction to the region of southern Italy where trulli and other typical stone architecture can be found. The Itria Valley with its towns and landscape and the town of Alberobello are described from an architectural point of view. The second section describes the different examples of building constructions in local stone of the Itria Valley, focusing on ancient and contemporary quarries. In this part petrographic and physical mechanical characteristics of the main kind of limestones are reported and discussed. The third part focuses on the main examples of stone architecture of Itria Valley, distinguishing the historical rural buildings from the other historical civil ones. In this section particular attention is given to best practices of evaluation action, protection rules and restoration methods for stone heritage in Itria Valley and Alberobello. This book serves as a useful source of information to geologists, archaeologists, architects, historians and stone industry operators specifically, and to academic and non-academic communities, travellers, and tourism industry operators in general. The book will also be of interest to students, researchers, and rock enthusiasts spanning all age groups and academic levels.

This book is about the stone used to build the castles of Edward I in North West Wales. It provides a description of the available geological resources and the building materials used in the construction of Caernarfon, Conwy, Harlech and Beaumaris Castles. It takes a broad view of this subject, placing the stone used in the castles in the context of both earlier and later buildings across the region of study, from the Neolithic up until the present day. The book will serve as a useful source book for geologists, archaeologists, architects, representatives of the natural stone industry, historians and cultural heritage management professionals specifically and for academic and non-academic communities, travellers and tourism industry operators in general.

There are many UNESCO World Heritage Sites in Germany. Most of them are built with natural stones. These sites are commonly presented to the public with a lot of information regarding historical, cultural and artistic aspects. Mostly, there is no focus on the main building material if it concerns natural stones. This work aims to show that it is precisely the natural stone that lends the sites their distinctive character. The used stones demonstrate the context and the interaction with the geology of the surrounding countryside as well as possibilities of transport and treatment. They reflect the culture and society at the time of the building phases. The second part of the work presents the most important stones that were used at these sites, along with their occurrences, aspects of quarrying in historical times and of course their petrographical, mineralogical and technical features. It is shown how these features influence the weathering of the stones and how restoration of stones is carried out. The book will serve as a useful source book for geologists, archaeologists, architects, representatives of the natural stone industry, historians and cultural heritage management professionals specifically, and for academic and nonacademic communities, travelers and tourism industry operators in general.

This book discusses heritage stones which were used in the making of the architectonic heritage of Delhi and Agra, encompassing UNESCO world heritage sites and heritage sites designated as prominent by the Indian government. The most famous monument of the two cities is the ‘Taj Mahal’ of Agra. The book focuses on the geological characteristics of the famous Makrana marble, red sandstone and other sandstone variants of the Vindhyan basin and Delhi quartzite, the most widely used stones in almost all the monuments, as well as on their quarries. The work also aims to sensitise the public to protecting and preserving the architectonic heritage of these two densely populated cities in India as repositories of our past cultures and traditions. Identifying the nature and provenance of stones/rocks used in construction will lead to better restoration for future generations, in light of the deterioration of architectonic heritage through various natural weathering agencies and anthropogenic activities. The book will serve as a useful source book to economic geologists, geologists, archaeologists, architects, historians and stone industry operators specifically and to academic and non-academic communities, travellers and tourism industry operators in general. The book will benefit students, researchers, and rock enthusiasts spanning all age groups and academic levels.

This book is made up of contributions dealing with heritage stones from different countries around the world. The stones are described, as well as their use in vernacular and contemporaneous architecture. Heritage stones are those stones that have special significance in human culture. Examples include some very important stones that have been either neglected because they are no longer extracted, or stones that have great significance in commercial terms but knowledge of their national and/or international heritage has not been well documented. In this collection of articles, we have tried to spread awareness of architectural heritage around the world, the natural stones that have been used in its construction, and the need to preserve historical quarries that once provided the source of such stones. Historical quarries are linked to regional culture and tradition. Because of the specific technical and aesthetical characteristics of heritage stones, which have lasted for centuries, these historical quarries should be preserved to be able to use the stones for the proper restoration of monuments and historical buildings to avoid negative actions that can be observed in many places in the restoration of buildings, which are some times part of World Heritage sites. The final intention of this book is to continuosly grow the interest on this fascinating subject of heritage stones.

This Special Publication is dedicated to heritage stone: those natural stones that have special significance in human culture. Some stones that have had important uses in the past are now neglected because they are no longer extracted. Others are still commercially important, but their heritage uses have not been well documented in widely available sources. The Heritage Stone Task Group of the International Union of Geological Sciences is working to establish a new formal designation of ‘Global Heritage Stone Resource’ to recognize those stones that have had internationally significant architectural and ornamental uses. The aim is to spread awareness of the cultural heritage aspects of these stones, to help to encourage continued supply for maintenance and repair of important monuments and to preserve historically important quarries. The aim is neither to promote nor to limit these stones for new construction: in some cases continuing commercial use might help to ensure future supplies for building conservation purposes.
