The Subway in Moscow deserves a special visit.   You will have the opportunity to go thru these images and appreciate Moscow's Subway Stations Architecture...

Baumanskaya - Work on the Subway started in 1930 - Its length is approx. 256 km (159Miles), actually the subway has  138 stations, and the most beautiful stations are located near the center of the capital.

Very simple trick but quite spectacular.Hope you'll manage to guess how i've done it :] The coin "stucks" in the matchbox after every time i rub it..
