YEARS  AGO
Doorways in the temples were designed to be closed from the inside to keep things out of the sanctuaries -- not inside.

Small "windows" in the walls that link one area inside the temple with another or with an exterior shrine are commonly called Oracle Holes.  Some scientists think that people would have come to the temple to get questions answered or dreams interpreted by some unseen voice of authority.  The ancient Greeks practiced this.

Other holes around the portal stones are in matched pairs and probably supported hinges for doors and heavy locking poles.  Some holes are connected to each other to make a small channel inside the stone, as if to hold a rope for tying.

Perforations called "libation holes" frequently penetrate the paving stones near the entries. Other ancient cultures poured liquids onto the ground as a libation gift to the earth: a little bit of milk or water, wine or oil, or even blood.  Maybe the temple people had this practice too.
