On the occasion of the European Heritage Days 2023, Saturday and Sunday 16 and 17 September, the Brézé domain with its unique troglodytic network will be accessible free of charge. You can visit the castle on the surface with its furnished rooms as well as the entire underground system housing the very first castle but also the hidden commons at the bottom of impressive dry moats of 18 meters depth, dug from the 15th century. At the end of this 2-hour journey, the wines of the estate can be tasted in the brand new cellar, located in the old orangery.
