An astronomical complex or commemorative astronomical complex is a series of man-made structures with an astronomical purposes. It has been used when referring to a group of Megalithic structures that it is claimed show high precision astronomical alignments. For the study of Archaeoastronomy, such complexes of similar structures are required for adequate measurement and calculation to ensure that similar celestial sightlines were intended by the designers. These arrangements have also been known as observational, ceremonial or ritual complexes with importance for the study of ancient cultures who had practical knowledge but no science. It has been suggested prehistoric peoples designed and built such complexes to seek protection from natural disasters from their ancestors, whose spirits were believed to dwell in the sun and moon. It has gained some acceptance that these ancient societies chose locations, shapes, colours of stones, nearby hills, mountains and landscape features to create complex structures with astronomical alignments to improve their relationship with the natural world.
