European Heritage Days (Journées Européennes du Patrimoine) is a major cultural festival during which hundreds of historic buildings, ministries, museums, and restricted government residences in Paris open their doors to the public for free visits.
The event’s main highlight is the unique opportunity to gain legal, free access to places where entry is strictly prohibited for the general public on ordinary days (such as the French President’s office).
Important tips for visitors — Advance booking: Although admission is free, mandatory advance online registration is required for the most popular sites (such as the Élysée Palace). Booking slots on the official websites are snapped up within minutes of becoming available (usually in late August or early September).
Walk-up lines: Huge lines form at locations that do not require reservations. It is best to get in line for the top palaces 45–60 minutes before opening.
Security: Strict security screening is in place at the entrances to all government institutions; carrying a passport is mandatory.
