A distinction that often pits the residents of the capital against those of its small (or large) ring, which the high commissioner for Planning intends to resolve by making Paname an expanded and united city. A completely wild project that could very well transform the daily lives of many of us.


A capital with new borders

In a note published this Thursday, June 4, 2026 , Clément Beaune shared his aspirations for the future of the City of Light.

This would be a complete revolution that could reduce the levels to 3 (compared to 5 or 6 today): the region, the city of Greater Paris, and the famous districts, which would each group about 200,000 residents. A change that, as we can picture, might stir up some controversies if it were to happen…
