»City, Country, River« is this year's theme for the 10th Children's City. Before it can be built lifelike in summer, groups of children from the primary schools in Glaucha, Nietleben and Kröllwitz will design initial building proposals on a model size. Dreams of large tree houses and a Quidditch stadium for the new city will come true. But there will also be animal rescue stations. Then there is the need for toilets and hospitals. Where is all this going to go? As part of the winter holiday programme at the Krokoseum, ideas and visions were discussed, researched and tested in a child-friendly manner.
