The conservation of monuments and historic sites is one of the most challenging problems facing

modern civilization. It involves, in inextricable patterns, factors belonging to different fields (cul-
tural, humanistic, social, technical, economical, administrative) and the requirements of safety and

use appear to be (or often are) in conflict with the respect of the integrity of the monuments. The

complexity of the subject is such that a shared frame of reference is still lacking among art histo-
rians, architects, architectural and geotechnical engineers. And while there are exemplary cases of

an integral approach to each building element with its static and architectural function, as a mate-
rial witness to the culture and construction techniques of the original historical period, there are

still examples of uncritical reliance on modern technology leading to the substitution from earlier
structures to new ones, preserving only the iconic look of the original monument. Geotechnical
Engineering for the Preservation of Monuments and Historic Sites III collects the contributions to
the eponymous 3rd International ISSMGE TC301 Symposium (Naples, Italy, 22–24 June 2022).
The papers cover a wide range of topics, which include:
- Principles of conservation, maintenance strategies, case histories
- The knowledge: investigation, monitoring and performance
- Seismic risk, site effects, soil structure interaction
- Effects of urban development and tunnelling on built heritage
- Preservation of diffuse heritage: soil instability, subsidence, environmental damages
The present volume aims at geotechnical engineers and academics involved in the preservation of
monuments and historic sites worldwide.
