Heritage is an important cultural, social, and economic resource that enriches global societies. Architectural heritage is present in practically all geographical areas, towns and villages. Monuments and buildings occupy prominent places in the territory, reflecting the past of societies, history and tradition, worthy of preservation. However, these built assets are under constant threat of destruction, disappearance, or deterioration.

There is a need for further research and development of new methodologies to detect risks and control the deterioration of historic monuments and buildings. The protection, conservation, restoration, management, research, dissemination and enhancement of world Cultural Heritage (CH) must be approached from an interdisciplinary and multidisciplinary perspective. The final objective of the AVATAR project is to make a quantitative leap in the intervention works (liberation or consolidation) and conservation (restoration or reconstruction) of abandoned, destroyed or ruined buildings, through a methodology that allows exploring the cultural and social meaning of these architectural assets or its use or function. In this way, it will be possible to carry out these works while maintaining the integrity and identity of the property. At present, there is not a standard policy for the reconstruction of destroyed cultural heritage.
