The Organization of World Heritage Cities (OWHC) is pleased to announce the launch of the 2026 edition of the Jean-Paul-L’Allier Prize. This prize recognises outstanding projects implemented by member cities that contribute significantly to the enhancement, regeneration and sustainable management of their historic centres.

For this edition, the Prize invites member cities to submit structural and cross-cutting projects that promote the regeneration of historic centres through strategies focused on habitability. These initiatives must have already been implemented and place residents at the heart of public decisions, demonstrating concrete and lasting effects on their quality of life.

The mayor of the winning city will be a guest of honour at the 18^th World Congress of the OWHC, which will take place in Marrakech from 26 to 29 October 2026. During this event, the winning project will be announced and presented.

Applications are open until 8 May 2026. Interested cities must submit their applications in accordance with the criteria set out in the technical document below. On 11 June 2026, the candidate cities and their projects will be announced across the OWHC network, for evaluation by a jury.
