I will take you on a journey back to the time of the Rhaetians, who gave this region, the Rätikon, its name. On the high plateau of the Tschengla we find 4 important stone circles from the megalithic culture, which show us the way back to prehistoric times. I will show you the best, most powerful and beneficial places in the stone circles. But how were the stone circles used by the Rhaetians as astrological calendars, celestial observatories or places of worship? Were there also mysterious gates for time travelers? We will find the answers.
