The firefly cave: opening postponed

Postponed opening

In this new space, dedicated to the most famous of magicians, visitors to the Lucioles Cave in Altkirch will be able to discover decors inspired by JK Rowling's books and movies of the saga: the Diagon Alley, the magic shops, the magic room and many other surprises!

This is the most tedious decoration ever made in Altkirch, having required more than 10 months of work, the thoroughness of the details of which will surely surprise you.

For this 2020-2021 season, the Cave of the Fireflies of Altkirch has been given a makeover: new settings are being installed in the second part of the world of Harry Potter: discover the Diagon Alley and many other surprises! In addition, all the windows will be animated for visitors and presented at the same times as the cave.

Admission to the nearby train world exhibition is free. Take the opportunity to take a family walk there when you have a little free time! The exhibition on the world of trains has also grown considerably; it has now left rue des Boulangers to move to Place des 3 Rois with a new, entirely refurbished model decor.

To get your own opinion on this extraordinary place, do not hesitate to take a tour on the opening dates and times during the Advent period.
