This book is the first of a series of volumes on Built Heritage and Geotechnics, intended to reach a wide audience: professionals and academics in the fields of civil engineering, architecture, restoration and cultural heritage management, and even the wider public. The present volume provides essential information on the history of the construction of theGhirlandina Tower in Modena, the techniques involved and the restoration works, and proves how the interaction with the supporting soil may explain the reasons behind the corrections that masons implemented during construction, the pattern of settlements suffered by the tower and the Cathedral and their mutual interaction.
In addition to the above, there is one particular aspect that should capture the interest of a wide readership: in 1997 the Cathedral and the Ghirlandina Tower were included in the UNESCO World Heritage List, and it was recognized that the creation process shared by Lanfranco and Wiligelmo is a masterpiece of human creativity, in which a new dialectical relationship between architecture and sculpture was created in Romanesque art. The Modena complex bears exceptional witness to the cultural traditions of the 12th century in northern Italy's urban society, its organization, religious character, beliefs, and values all being reflected in the history of the buildings.
1. Introduction. 2. Historical notes on the construction of the Cathedral and the Ghirlandina Tower. 3. Previous restoration works in the 1970s. 4. Planning the new investigation studies and the restoration works. 5. The soil as "material with memory": a key to explain the settlements of the tower and the cathedral and their interaction. 6. A primer on soil‐structure interaction and soil condition effects. 7. An advanced approach to assess the behaviour of structures under dynamic loads: dynamic identification analyses. Appendix: Introductory notes on problems related to the stability of historic towers.
This is a series of short books on specialized topics that fall under the overarching theme of built heritage and geotechnics, like well documented case studies of restoration works at one specific site or of a monument, or detailed overviews of construction techniques, intended as a material witness of knowledge of the historical period in which the monuments were built, or specific conservation / preservation works.
Preservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical and economical aspects in inextricable patterns. The complexity of the topic is such that a shared framework of reference is still lacking among art historians, architects, structural and geotechnical engineers. This is proved by the fact that, despite there being exemplary cases of an integral saving of any structural components with its static and architectural function, as a material witness of the knowledge, the culture and the construction techniques of the original historical period, there are still examples of uncritical confidence in modern technology which leads to the replacement of previous structures with new ones, which only preserve an iconic appearance of the original monument.
For this reason publishing short books on specialized topics, like well documented case studies of restoration works at one specific site or of a monument, or detailed overviews of construction techniques, intended as a material witness of knowledge of the historical period in which the monuments was built, or specific conservation/preservation works, will be of great value.
