It's one of the major cultural events of the autumn : a weekend of strolls, discoveries and games. Throughout Paris and theÎle-de-France region, thousands of official, historical, cultural, artistic and religious sites open their doors to the general public - and most often, free of charge!

On September 19 and 20, 2026, the Heritage Days will center on the themes "Heritage of Photography" and "Heritage at Risk". Discover the venues and activities to explore over the weekend, tied to this year's themes.
