Imagine exploring extraordinary monuments after dark—this is exactly what awaits us from April 17 to 19, 2026, during the Night of the Monuments. Following the success of the Night of the Castles and the Night of Museums, this new initiative led by Dartagnans offers a rare chance to visit numerous historic buildings in the evening and experience them in a whole new light, a tradition that has gained momentum since last year.

For three nights, abbeys, manor houses, , theaters, museums, and even industrial sites— whether historic or modern — will open their doors for exclusive nighttime tours. This is a rare opportunity to discover France’s heritage in a unique atmosphere, illuminated by spotlights, torches, or specially designed lighting for the occasion.
