Conservation Documentation and Non-Invasive Research on Hans Memling’s “The Last Judgement”

The most valuable work in our collection is currently undergoing a series of non-invasive studies that will help us provide it with conditions in line with the latest preventive conservation standards and ensure that it can be safely made accessible to visitors.

We have been carrying out advanced research and documentation of Hans Memling’s The Last Judgement triptych since February 2025. Our aim is to conduct a detailed assessment of the work’s condition using the latest technological tools. This multi-stage project is being carried out by the Conservation Department, with the particular involvement of the Painting Conservation Studio, which is undertaking an in-depth examination of one of the most challenging objects in the museum’s collection.

Our overriding priority is to ensure the maximum safety of the triptych. Comprehensive documentation and digitisation are key elements of a long-term strategy for protecting and making this exceptional cultural heritage object accessible to the public.

As part of the project, we are working with the Jerzy Haber Institute of Catalysis and Surface Chemistry of the Polish Academy of Sciences in Kraków on the advanced digitisation of the triptych using a Hirox 3D digital microscope. This highly precise instrument makes it possible to obtain high-resolution images of the painted surface, enabling the analysis of the smallest details and micro-damage. Imaging plays an important role in conservation documentation, creating a valuable reference base for future analyses. Digitisation at this level is not only a means of safeguarding cultural heritage, but also a step towards a better understanding of the work and making it more widely accessible.

Together with experts from the Jerzy Haber Institute and the Getty Conservation Institute, we are planning to carry out research using Digital Speckle Pattern Interferometry (DSPI). This technique makes it possible to observe microscopic deformations of the surface of the artwork caused by ageing processes and external factors. Comparing the current results with measurements taken in 2015 will enable us to assess the work’s condition precisely and formulate recommendations for further action. Based on this analysis, we will be able to make an informed decision about the safe future display of The Last Judgement.

We will keep you informed about the progress and results of the project.
