Some say they were going to test satellites and space shuttles inside this tower, other people believe it was connected to telescope testing. The most interesting version is that in this tower they were going to test lasers and probably military ones, which could destroy upcoming ships.
In the distance you can see a crane and the tower.
Unfortunately, in the 90s the crane was cut up into pieces to be sold as scrap metal (a view from Google Maps).
The story of this construction began when an optical institution decided to grab a nice piece of forest near the lake.
