The Paris metro line 14, the most recent one, opened as late as 1998 and the stations are of a very different design compared to the more traditional ones, considering that most of them date from 1900 and a few years after that.
In one of the line 14 stations,“Madeleine”, there is a wall decoration offered by the Moscow Metro in 2008. It tells the story of “Ryaba, the hen” and a golden egg.
As an exchange, the Paris Metro offered a copy of its specific Guimard (see previous posts here and here) designed metro entrances to Moscow. (I stole this picture from here.)
The Moscow metro is more recent than the Paris one, the oldest lines date from 1935. Some stations are fabulously decorated. I took a number of photos from some of the Moscow stations during my visit there last September…
… as well as of the Saint Basil’s Cathedral, which somehow is represented in the Moscow wall decoration.
