Rainforest

Well inside Atocha station is a rainforest. Someone had the genius idea of filling out the space with trees, a pond, turtles and fish. It was extraordinary. It was such a peaceful place. It was however very humid. The air outside in Madrid is very dry and so you don't summer so much in the heat. In here it was maybe 10 degrees cooler but I was already sweating after a few minutes. But it was a small sacrifice. Well done, Madrid. Genius. What was that with London's £150m garden bridge?
