In the meantime it is a good tradition that visitors of Peter’s rock-garden bring along a stone. By now stones are accumulated from all over the world.
Also for the labyrinth there are again and again beautiful or valuable pieces. As happened on July 8, 2008, when two ladies from Vienna announced to visit the labyrinth. Peter then always selects a special place in the labyrinth and can also remember still years later each individual stone and its origin.
And the visitors hopefully also?
