Toi, toit, mon toit: the festival for discovering Seine-Saint-Denis from the rooftops

The rooftops of Paris have always had a mysterious side, not really accessible to the general public! The roofs of Seine-Saint-Denis will be opening their doors to you from June 27 to 29, 2025, for the first edition of the free "Toi, toit, mon toit!"festival, featuring walks, tours, workshops and festive events over three days. We'll be taking to the skies to discover the converted roofs, perched alongside their occupants or architecture and heritage professionals.

Plaine Commune is keen to support initiatives around rooftops, which are often under-exploited spaces and can become places for life and culture, expanding the possibilities in already densely populated cities. To discover them in a playful way, take advantage ofparticipative and unusual events proposed by local associations, artists or collectives, such as cyanotype workshops, beekeeping, tastings, readings, aperitifs...
