My city Jena
These buildings of the GDR time are behind Jena-Lichtenhain in the Jenaer Forst, west of the city. They are mystic because now it is a lost place and they are surrounded by trees. Close by you find some ponds hidden in the forest which also belong to the former military testing ground (renaturierter Truppenübungsplatz). The next village is Coppanz and Ammerbach.
