Thousands of co-châtelains from all over the world

In 2017, thousands of people fell in love with la Mothe Chandeniers. A love that has traveled the world, cultures, religions and gave birth to a project never seen before: to collectively save a castle.

Today, these women and men have become the co-chatelains of this unique castle in the world. New guardians of the soul of the castle, these thousands of enthusiasts all have a common goal: to revive the Mothe Chandeniers by uniting their passion and their ideas in a large collective project.

A concept created by Dartagnans x Adopte un château

Together, these two heritage main actors have been using their knowledge of financial engineering, legal editing and development of the heritage sector for two years to bring out this new model of preservation.
Dartagnans and Adopt un château carefully choose the endangered places, build economic development models and unite together the local actors to build these ambitious projects. They are in charge of the day-to-day running of the project.


Dartagnans is the innovative start-up that reinvent heritage preservation. Positioned as a transversal actor of the sector through its three activities: crowdfunding, collective purchase of monuments and cultural tourism
