The critical condition of detaching historical murals in the Convent Müstair (Switzerland) prompted a series investigations and conservation actions over last 40 years. After percussion tests 1984/1992, an advanced technology time-average TV-holography has been applied 2000 2005. primary aim was to substantiate if which extent is progress. This case study explores characteristics limits traditional TV-holography. Extensive mappings by both techniques are carried out on two different structures wall paintings. comparison shows that so-called test – when combined with close experienced observation reveals holistic picture general threatened painting. Time-average TV-holography, other hand, yields highly accurate relative information spatial distribution detached areas. Therefore, it apt provide exact answer question detachment progress or not.
