Rambam - Hilchot Beit Habechirah 7:11b The Laws of God's Chosen House - , To achieve the biblically ordained legal demarcations of geographic holiness, we are forced to superimpose the ancient Sinai's schematic onto Jerusalem's municipal layout.

This enables us to later map out the footprint of the proverbial Food Courts and Activity Zones designated for unique Mitzvah performance!
