A nondescript city neighbourhood has a secret in one of its apartment blocks: an alien-infested spaceship.
Barcelona-based Sci-Fi fan Luis Nostromo loves the aliens films so much, he has built his own museum.
Luis saw the original Ridley Scott film when he was young and a life-long passion developed.
The 43-year-old has now almost completed his homage to the film series.
It includes homemade sets as well real props from the movies.
Luis says: "I hope to finish the last details during 2020".
