Based on topographical and textual considerations, Conder argued that it would be dangerous and unlikely, from a town-defense point of view, for the walls to have previously been east of the Church of the Holy Sepulchre, concluding that the Church would have been inside the city walls and thus not the authentic tomb of Christ. He instead proposed that the true Calvary was the "rounded knoll" above Jeremiah's Grotto (i.e. Skull Hill). He based this identification on several arguments. First of all, since the Gospel according to John places Golgotha in the near vicinity of a garden and a tomb (John 19:41-42) Conder argued that Golgotha must be close to the necropolis found just north of Jerusalem, near the main road to Nablus, "among the olive-gardens and vineyards of Wady el-Joz". Secondly, Conder proposed that Calvary was the public place of execution and especially noted that Sephardic Jews had regarded the site next to Jeremiah's Grotto as traditionally being a place of stoning, which he saw as corroborative evidence that it was indeed "Golgotha". He also pointed to a Christian tradition which associated that general area with the martyrdom of St. Stephen as additional evidence that it was a public place of execution during the New Testament era. Conder actually downplayed the supposed resemblance to a skull which he viewed as immaterial, remarking: "I should not like to base an argument on so slight a resemblance". In his writings Conder refers to Skull Hill by the Arabic name El-Heidhemiyeh which he interpreted as "the rent", and which he proposed was a corruption of El-Heiremiyeh - "the place of Jeremiah". However, later research has shown that the name is actually a corruption of El-Adhamiyeh, named after a zawiya which according to Muslim tradition was founded by the celebrated Sufi saint Ibrahim ibn Adham.
