On a journey of discovery to the DA, Kunsthaus Kloster Gravenhorst. There the riddle of the green potsherd has to be solved! In the historic walls of the former monastery you will gradually find clues to solving the tricky task. There is a lot to discover and experience, because after all you are moving in a medieval monastery. Do you want to be the miller's daughter Clara, Knight Konrad or Princess Oda? First you choose a character: then you set off.

Exciting challenges await you at 18 stations. They are not only virtual, but can also be mastered very practically on site in the field: Build a water sculpture at the dialogue fountain, dig up a grave slab and calculate the time according to the sundial. You can copy the seal of the monastery, listen to the sounds of the kitchen and scream very loudly - louder than the annoying noise of the motorway, which today passes very close to the monastery. You have to balance as far as possible, hop at another station and find treasures. At the Back- und Brauhaus you will find out from which grain certain foods are made. Animals that cannot swim at all got into the monastery pond. A real knight in the Middle Ages had a thick plume on his helmet. There are also hints to solve the puzzle hidden here. In between, however, you absolutely have to repair the mill and start the steam engine - otherwise you will miss out on important game points. Then you go on an imaginary journey. You will discover traces of secret messages on the church walls and unravel the alphabet salad in the library. And you have to measure the bridge with your feet to collect important clues. When you have completed all stations, the riddle about the green potsherd will be solved!

There are small audio clips to help you find your way around the monastery grounds. They take you into the history of the monastery and tell you what life was like in the Middle Ages - without electric light, running water or fish fingers.

Each game station revolves around its own, self-contained story. The game is particularly fun on site, but with the app you can also play it from home or on the go. And if you have to leave earlier and you still lack game points in Gravenhorst, you can finish the game at home.
