This audio guide about the most important and beautiful trees of the Nordertor was created as part of a project by the 7th-grade elective science course at IGS Nienburg during the 2015/2016 school year. The starting point of this audio guide is the beautiful Turkish hazel tree in the courtyard of the Friedrich-Fröbel-Schule / IGS Nienburg building. For those not affiliated with the school, this specific starting point is only accessible outside of school hours; we kindly ask you to respect this. Enjoy our audio guide about the trees of the Nordertor!
