they are pics of moscow metro.
each one is built according to a unique theme. For example in station of Mendeleev (who found the periodic table of elements) u'll find atomic structures of elements hanging everywhere.
no 2 station are same
mn i live there for 5 years and many times travelled by moscow metro, but i didnt see this..
paveletskaya to university - belaruskaya nearly all metro station structures are same. not like this. maybe this is another part where I didnt travel. where i travel usually is ugly looking
