None. Near my city never had the positions of S-75. That why i put "memorial" in quotes.

This missile is located in a park among other weapons of the 50-60's(T-55, BTR-70, L-29).
It's park called "Victory Park". And It means "victory in WW2"!
But that is absurd. This park is absurd. Stupidity of the local authorities.
But I'm grateful them for the missile =)
