Fraser's "The Golden Bough" (as sourced by Rayelan) is not the only source corroborating Jana's information on human sacrifices in architectural structures:

"In olden times, when a new building of any importance was started, it was customary to slay a human being as a "foundation sacrifice." This provided a ghost spirit to watch over and protect the structure. When the Chinese made ready to cast a bell, custom decreed the sacrifice of at least one maiden for the purpose of impriving the tone of the bell; the girl chosen was thrown alive into the molten metal."

"It was long the practice of many groups to build slaves alive into important walls. In later times the northern European tribes substituted the walling in of shadows of a passerby for this custom of entombing living persons in the walls of new buildings. The Chinese buried in a wall those workmen who died while constructing it."

"A petty king in Palestine, in building the walls of Jericho, "laid the foundation thereof in Abiram, his first-born, and set up the gates thereof in his youngest son Segub." At that late date, not only did the father put two of his sons alive in the foundation holes of the city's gates, but his action is also
recorded as being "according to the word of the Lord." Moses had forbidden these foundation sacrifices, but the Israelites reverted to them soon after his death. The twentieth-century ceremony of
depositing trinkets and keepsakes in the cornerstone of a new building is reminiscent of the primitive foundation sacrifices."

Human sacrifice was a holdover from the once widespread practice of cannibalism. And it persisted throughout many parts of the world, including China, India, Egypt, among the Hebrews,
Mesopotamians, Greeks, Romans, Africans and Australian tribes. The native American peoples (particularly those in Central and South America) also practiced human sacrifice and cannibalism
prodigiously.

Human sacrifice was ultimately supplanted by other forms - money offerings being the form that appears to have persisted.

It's all a bloody, atrocious business, arising out of humankind's misperception of the true nature of God - which is that of a loving Creator whom we may reach individually by faith and faith alone. No flesh, money pledges or intercessions by priests, please. Simply faith.
