Monument Jeu d'Enfant 2026: a historical detective game at the Hôtel de la Marine

The magnificent Hôtel de la Marine is once again taking part in the Monument Jeu d’Enfant event, this weekend of October 17–18, 2026. On the agenda for these special days: a grand game for the whole family...

For the first weekend of the All Saints' vacation season, parents and children are taking part in a not-to-be-missed event that's as much fun as ever: Monument Jeu d'Enfant. Numerous monuments across France are opening their doors to curious youngsters, to help them discover our exceptional heritage in a fun and educational way.

This year we’ve got plans for Saturday the 17th and Sunday the 18th of October, 2026, to tour the Hôtel de la Marine, in the very heart of Paris. This magnificent landmark invites families to discover its history through a range of tours and workshops for the family, revealing all the secrets of the site.

Located on Place de la Concorde, the Hôtel de la Marine was originally designed as a furniture depository for the Kings of France. After the French Revolution, this exceptional setting was used as offices for the Ministry of the Navy. It wasn't until 2015 that the Navy left the premises. The buildings were then restored and opened to the public as a national monument and exhibition space.

Advance reservations are required to take part in the activities offered by the Hôtel de la Marine during this event. Get your tickets now to make sure you don't miss out on any of these fun activities, which should delight the whole family.

Here's what's in store for this weekend of discoveries at the Hôtel de la Marine:
