“Golgotha” means skull

Golgotha: the Hebrew name of the spot at which our Lord was crucified. (Matthew 27:33; Mark 15:22; John 19:17) By these three evangelists it is interpreted to mean the "place of a skull." Two explanations of the name are given: (1) that it was a spot where executions ordinarily took place, and therefore abounded in skulls; or(2) it may come from the look or form of the spot itself, bald, round and skull-like, and therefore a mound or hillock, in accordance with the common phrase --for which there is no direct authority-- "Mount Calvary." Whichever of these is the correct explanation, Golgotha seems to have been a known spot.
