To get to the observatory, it is necessary to get to the district center Kstovo - a small town down the Volga. More walking and here it is - an abandoned observatory is actually slightly longer path and fun, so see photo story with my own eyes.
Monument to Lenin.
Sprinkle on the guy
There Kstovo and a business center
All the way forward - on foot. The village of Great Enemy. The name is connected likely with a huge ravine behind the village.
