Runic stones are hidden all over the 11 hectares. If you find these engraved stones and photograph them, you win points and clues. A few additional runes are hidden over the whole of the territory of Haut-Saintonge. You will discover them with items found in the Park. The last Rune represents the Treasure. It’s said that it is situated in a place that, precisely, cannot be found but like all indecipherable secrets, a player will one day necessarily find it. It’s up to you to play!
