The playground near Budolfi Domkirke, The snake with the apple

Here children can crawl, climb and slide. You'll find a play tower with a slide in the shape of a snake wrapped around an apple. You can crawl inside or outside the apple and the snake and find some good hiding places.

Can you guess why there's an apple and a snake right next to Budolfi Cathedral? Make sure the snake isn't playing tricks on you.
