To mark the 42nd European Heritage Days, the Hôtel de la Marine will be opening its doors free of charge on Saturday 20 and Sunday 21 September 2025.

This is an opportunity to discover or rediscover the following tour routes:

  • The " Appartements des intendants au son du Confident" tour, which is open by reservation, will enable you to explore the 18th-century flats of the Intendants of the Garde-Meuble de la Couronne, as well as the state rooms and the loggia.
  • The Al Thani Collection tour, with free admission subject to availability, takes in the Seven Heavenly Senses exhibition, the sumptuous state rooms and the loggia.

To be discovered during the Heritage Days

At the same time, visitors can take advantage of the weekend to admire Le Labyrinthe, a monumental installation by Jérémy Pradier-Jeauneau created especially for the Hôtel de la Marine as part of Paris Design Week.

With Le Labyrinthe, Jérémy Pradier-Jeauneau has created a sensitive and poetic installation, conceived as a journey in three chapters between the main courtyard, the ceremonial rooms and the loggia of the Hôtel de la Marine.

It's a vibrant tribute to French craftsmanship and design, to the myth of Daedalus, and to the history of the building itself, which was the Crown's furniture repository in the late 18th century.
