The mystery of the Japanese bacteria living on Rembrandt’s ‘The Night Watch’

Researchers from the Rijksmuseum and Artis-Micropia are studying microorganisms on Rembrandt's 'The Night Watch'. They collected 60 samples revealing skin and soil bacteria, including a surprising species from Japan. This research is part of Operation Night Watch, aimed at restoring and analyzing the painting. The study highlights the importance of microbes and their role in art conservation. The findings will inform ongoing restoration efforts at the Rijksmuseum, where conservators are carefully removing a 1970s varnish layer. A related exhibition at Artis-Micropia will showcase the painting's microbial life until May 2027.
