At multiple sites in the Middle Mountain we find skewer holes in granite stone. They have a regular diameter and do not have a perfect circular shape. They are slightly heart shaped.
The solid granite megaliths look like they were once soft and malleable before hardening. It seems like they were molded around the skewer hole like you would melt a marshmallow on a stick over the fire.
At the pyramid of Stryama the skewer holes are located at the base of the pyramid. These stones date back to the earliest Lemurian epoch of megalith building. There are several skewer holes in a single megalith as well as other similar holes in another megalith nearby.
At the Double Pyramid of Bania there are skewer holes including one that is located in a granite stone that looks like it was about to be cut out like a chunk of glass.
