Through these pages, various characters who lived in the city at different times and became Madrid residents circulate, each one in their own Madrid. The Madrid that they knew is mixed with the current one in a map of translucent layers composed of places that are still there and others that are no longer. Because Madrid, above all things, is made of those who came to stay and those who continue to do so every day. A kaleidoscope of history, memories and future, in continuous movement.
