The Alentejo is one of the few places in Europe where the ‘ light pollution ‘ still is minimal and where you can still enjoy a beautiful starry sky with millions of stars.
With light pollution is meant the stray light of a large number of light sources such as street lights, neon sign, car headlights, lighting of buildings, greenhouses, airports, etc. etc. In an urban environment it is not really more dark and most stars are no longer visible. According to researchers can most of the world’s population no longer see the milky way! Whole generations of children grow up without ever having seen a sky full of stars.
