La Sagrada Familia in Barcelona is truly an extraordinary work, one of the things you must do in the Catalan capital. It is important that it is unfinished but it is amazing what is already there. On the facades it tells the story of Jesus, from birth until death. Inside there is the heavenly Jerusalem, inhabited by the Lamb, the son of God who has finished his earthly suffering and lives in Paradise, finally rescued. The Sagrada Familia is a huge Christian symbol, a kind of Bible story stone.
