There were various creative hands-on activities on the theme of spring in the city center on Sunday. Particularly hard-working people had the chance to win a little surprise. All the activities could be found on a stamp card. With just three stamps collected, the card could be exchanged for a small spring gift at the gtm ServiceCenter. Visitors were able to show off their creativity by painting clay pots, among other things. If you were handy, you could even build your own insect hotel for your garden or balcony at the NABU station. At Berliner Platz there was the opportunity to plant your own flower pots. There were 5 stations in total - all stations were located at different places in the city center.
