On your way through the Celtic village, you will find image targets at various locations, which you can use to access additional digital content and two adventure games within the Saltwelten app. Scan the square black-and-white images with the scan function in the Salzwelten app and immerse yourself in the world of the Celts. If you want to explore the Celtic village with the audio guide, follow the numbers on the orange signs with headphones, or scan the square black-and-white images with the scan function in the Salt Worlds app.
