What is the world’s most impressive metro? Many people would name the other-worldly Stockholm underground. My Ukrainian friends, of course, will recommend Kyiv: its pompous socialist modernist stations feature folk motifs and vaulted vestibules. Berlin doesn’t top such ratings but still has quite a few stations worth visiting.

And one more thing: I dared to give nicknames to the stations and hope they’ll make you smile. Feel free to write in the comments below which station (or nickname) you enjoyed the most.
