Does anyone has idea/knowledge, why neolithic temple stones would have these small holes? They are facing to sun, other side of the stones is flat. Smaller object were drilled all over, not just one side. I saw these in Ħaġar Qim, Malta:
Such stippling is a common feature at prehistoric Maltese sites. They are often considered a primitive decorative pattern - somewhat of a forerunner of a modern art form.
It is the best preserved of all the Maltese temples ... The two left-hand lobed chambers are linked by a trilith niche of stones decorated by stippling; the inner of these two chambers is subdivided and in it stands two betyls, or pillar altars.

The device of stippling the background with an infinitude of tiny hammer-pick holes exquisitely sets off the boldly rounded curves that seem to have been a happy obsession with these artist-masons.

However there is no real way to be sure about their purpose. Some suggests, for instance, that a row of the dots counted the number of days between equinoxes.
