Стокгольмське метро приваблює туристів своїми розписами

Sweden 🇸🇪

The metro is the most unusual attraction in Stockholm, it is also popular here for tourists, as are palaces, churches and the old town. 

Going down there, you seem to find yourself in huge painted caves with Roman sculptures, fountains and funny installations. Therefore, it is no coincidence that it is called "the longest art gallery in the world."
