Sacred cult places were precisely aligned in prehistoric times, often at fairly long distances (10 - 20 km), following two geometric principles: straight line and – which was not known until now – horizontal equidistance. They were further interconnected, following above (sacred) principles, into networks, sometimes leading to constructions which are clearly not accidental. These alignments are most often not visible.

Cult places in prehistoric times were many different monuments and significant places such as dolmens, menhirs, cromlechs, cup stones, large erratic rock stones, "Kindlisteine", caves, abysses, earthworks, "sacred mountains", springs. Many prehistoric "settlements" and "fortifications" were rather cult places.

A very large number of positions of churches, chapels, oratories and crosses must have been replacing former cult places. However, for this exist relatively few indications or proofs.

Very many medieval towers and castles were constructed on prehistoric cult places, the main motive being probably the gain of prestige.

Also the Romans were likely conducting a somewhat active policy to occupy existing sacred places.

The religious geometry in prehistoric times leads to some new explanations, interpretations and discoveries, and indicates also the often artificial positioning of cup stones and creation or arrangement of some caves.

It is still unclear when such alignments of cult places started, also how they were exactly measured and achieved.

The orientation of many churches and chapels seems to go surprisingly to prehistoric cult places.
