In the middle of the Upper Palatinate, astronomy enthusiasts can wander through the universe. The starting point is the new 3D planetarium with an integrated observatory in the municipality of Ursensollen, one of the most modern astronomical facilities of its kind in Europe, according to the operators. The pavements are radially designed according to the image of the moon and orbits. The stargazers also attached great importance to compensatory areas of high ecological quality, including orchards and biotopes for reptiles and amphibians.
