Modern buildings are designed to have a lifespan of around 50 years. But in historical terms, that is a mere blink of an eye. We would like archeological sites like Pompeii, for example, to stand the test of time immemorial. Preserving sites such as this with the most basic materials represents a huge scientific challenge. As part of the “Pompeii Sustainable Preservation Project”, researchers from Technische Universität München (TUM), Fraunhofer-Gesellschaft and ICCROM will spend the next ten years investigating long-term solutions to prevent the UNESCO world heritage site of Pompeii from falling further into ruin.
