Atocha Station, Madrid

Not every indoor garden is housed in purpose-built greenhouse. Madrid's Atocha Station is a perfect example of a garden that is thriving in a general public space. One of Madrid's busiest train stations, Atocha is nothing like the chaotic transit hub you might expect. It does get very busy, but a massive garden boasting more than 7,000 plants representing 260 species gives it a tranquil atmosphere, even at rush hour. 

Tropical plants from all around the world are part of the display. There is also a pond that serves as a turtle sanctuary — in addition to housing a number of fish. The station itself is a classic structure that dates back to the 19th century. This oasis of nature and architecture in the middle of the hustle and bustle of modern Madrid is a worthwhile addition to any tourist's itinerary.
