Some cities introduce themselves from the plane. Paris gives you the Eiffel Tower. Rome the Colosseum. Barcelona Gaudí and the sea. New York the skyline.
And Madrid? Madrid doesn't really play along.
There is no single monument that explains it. No beach everyone walks to at sunset. No one photograph you have to take to prove you were here.
And perhaps that is exactly why it works. Because Madrid is one of those rare European cities where life itself is the attraction.
