Conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical, economical and administrative factors, intertwining in inextricable patterns. The complexity of the topic is such that guidelines or recommendations for ntervention techniques and design approaches are difficult to set.

The Technical Committee on the Preservation of Monuments and Historic Sites (named TC19) was established by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 1981, is supported by the Italian Geotechnical Society (AGI), and was renamed TC301 in 2010.

This book assesses the role of historic towers as symbols of community identity and how to best preserve this special cultural heritage. Well-documented, exemplary case histories highlight concepts of preservation, integrity, cultural heritage, dynamic identification techniques and techniques for long-term monitoring of historic towers, as well as provide examples of appropriate intervention measures.

The book will be of interest to professionals and academics in the wider fields of civil engineering, architecture and cultural resources management, and particularly those involved in art history, history of architecture, geotechnical engineering, structural engineering, archaeology, restoration and cultural heritage management.
