ART AND ARCHITECTURE - HISTORY - MARBLE - MOSAIC- SOVIET ART
Moscow Metro was designed under the motto to build a castle for ordinary soviet people. There are a lot of beautiful stations, with art and history connected to each one of them. We recommend to use Russia Beyond's list of the 20 most beautiful metro stations and just go and check some stations from their list https://www.rbth.com/arts/328682-moscow-metro-most-beautiful-stations. To avoid crowds, it is best to explore the metro on weekends or daytime on weekdays.
Another option would be a guided tour from our partner Strelka travel. https://www.strelkatravel.com/.
