Do you want to see how the rulers of Russia looked like from Rurik to Yeltsin? To do this, do not need to go much to museums and look for monuments. You need to visit the alley of the rulers of Russia. This is a project of the Russian military-historical society.
Coordinates in the title will lead you to the main entrance. The alley is available every day from 10 to 23 hours and is absolutely free.
To find the cache, you should carefully examine the busts of the four rulers (see photo) and find the numbers that were knocked back or side. These are not signs or small numbers that are on all busts. The required numbers are only on these monuments. A and D are numbers on the back. B - the difference of numbers on the side. C - the first (less) number on the side.
The cache is located at the coordinates: N55 45.(C/B + D + A) E037 38.((C-D)/(A+B) + A*A)
The cache is a magnetic microcontainer without a pencil(see spoiler - GeoCheck).
