Imaginambulles Festival

A 5th edition under the sign of Frank Margerin

For its 2026 edition, the Imaginambulles Festival once again takes over the Château de Rochefort-en-Terre on Saturday, June 13 and Sunday, June 14. The poster for this 5th edition is signed by Frank Margerin — iconic creator of Lucien and a major figure in Franco-Belgian comics — and J-Louis Hubert, who co-created it. An entire exhibition is dedicated to the world of Frank Margerin throughout the weekend.

About twenty authors gathered in the castle park

The festival welcomes about twenty comic book authors and illustrators for signing sessions and meetings with the public. Among the confirmed guests: Frank Margerin, J-Louis Hubert, Zanzim, Fabrice Meddour, Lucas Vallerie, Sébastien Morice, Gwénola Morizur, Sophie Ruffieux, Fred Simon, Didier Crisse, Cyril Trichet, Jérôme Pélissier, Carine Hinder, Catherine Latteux, Lionel Chouin, Christophe Babonneau, Ana Pich, Cédric Villani, Balouart, Wray, Jop and Ronan Pincemin. The styles covered range from classic Franco-Belgian comics to contemporary graphic novels, as well as youth comics, manga, and illustration.

Exhibitions, workshops, debates, and artist battle

Beyond the signings, the 2026 edition offers three exhibitions in the castle rooms, including the world of Frank Margerin. Free (or pay-what-you-want) comic and manga workshops allow visitors, children and adults alike, to learn drawing. Two debates are scheduled: Lucas Vallerie on Saturday at 3:30 PM and Ana Pich on Sunday at 3:30 PM. An artist battle pits authors against each other live at 4:30 PM, followed by a performance by a theater troupe at 3 PM. The day extends into the evening with aperitif concerts in the gardens, starting at 6:30 PM.

An exceptional setting in Rochefort-en-Terre

Voted “France's Favorite Village” in 2016, Rochefort-en-Terre offers a unique stone and greenery setting for the festival. The castle and its terraced gardens host signing stands, exhibitions, and entertainment, while the Imaginambar offers light refreshments, drinks, and musical entertainment in the park. Admission is entirely free.
