For the European Heritage Days, the Domaine national de Chambord offers a discount on the entrance fee of the castle.
For the occasion, many free activities await you inside the monument:

• "Favourite" guided tour (free, upon registration)
• Exceptional opening of the Renaissance attic (free visit)
• Exceptional opening of the Republican Guard stables (open house)
• Demonstrations and discussions around the Chambord Park perimeter wall restoration project.
  As a reminder:
  The entrance of the castle is free for children but also for young people of 18-25 years of age nationals of the European Union!
  Finally, the HistoPad visiting tablet is offered at a reduced rate during the JeP weekend (immersive views of the Renaissance castle, virtual treasure hunt, cartels of rooms and works, interactive plans, etc.)!
