France
Mayronne is a hamlet in the Corbieres hills, near Lagrasse. It hosts a stunning free sculpture trail five km long. There are permanent sculptures and an annual exhibition April - September. Sculptures are amusing, puzzling and breathtaking. The walk would be stunning even without the sculptures and it is a magical experience. Very few people know it's there.
