I keep taking pictures of the capitals underground stations...
spending more than an hour a day down there, the second city, I guess it's worth documenting it!
12 lines, 172 stations! On a normal weekday it carries 8.2 million passengers. Most of the lines were completed between 1935 and 1966 and it has some of the most admirable examples of socialist art!





Someone else did actually a much nicer work than me and reveals the real beauties those stations are.. just click on the M of the map.
