ESO Hotel at Cerro Paranal (or Residencia) is the accommodation for Paranal Observatory in Chile since 2002. It is mainly used for the ESO (European Southern Observatory) scientists and engineers who work there on a roster system. It has been called a "boarding house on Mars", because the desert surroundings are Mars-like, and an "Oasis for astronomers". It is not a commercial hotel, and the public cannot book rooms.
