Impressive complex with the lion towering over it. Well-paved paths lead through the complex. From the top you have a great view of the city of Belfort. At night the lion and the fortress are illuminated. Simply beautiful.

It is a monumental sculpture from 1880 created by Frédéric Auguste Bartholdi, the sculptor of the Statue of Liberty. Completed in 1880, it is entirely made of red sandstone. The blocks that make it up were sculpted individually, then moved to the cliff below Belfort Castle to be assembled there. Twenty-two meters long and 11 meters high, the colossal work dominates the local landscape.
