Background and content

The UNESCO report “Museums in the World” (April 2021) lists 103,842 museums worldwide. Studies show that 60% of them have problems in their storage (theft, disorder, lack of equipment, problems of clutter, access to collections, non-existent or incomplete documentation). As a result, the collections of these museums, 90% of which are in storage, are at risk, vulnerable and often unused.

In response to this situation, ICCROM, in partnership with UNESCO, developed the RE-ORG method in 2012, which has been applied in 33 workshops held in 23 countries. These workshops have led to the reorganization of 500 storage spaces, allowing secure access to the collections.

This programme was the subject of two resolutions passed at ICCROM’s 27th and 30th General Assemblies.

The 34th edition of RE-ORG will take place at the Museum of Sens in France from 27 November to 1 December 2023 and from 11 to 15 December 2023. The RE-ORG method was developed to provide capacity building for the reorganization of collections in storage.

The RE-ORG method has been developed and published to provide capacity building for reorganizing collections in storage.

As in previous editions, following two days of theoretical sessions, participants will completely reorganize the storage areas in the host museum, comprising twelve rooms.


The workshop will be coordinated by Gaël de Guichen, special advisor to the Director-General of ICCROM. The teaching team includes Florence Bertin, responsible for the collections department, Musée des arts décoratifs de Paris, Benoît de Tapol from the National Museum of Catalonia and Aida Nunes from the Museums of the City of Lisbon.


The workshop is aimed for 30 French conservation professionals working in museums whose storage needs reorganization. Based on their relevant experience, we selected to contribute to the workshop's success.
