This is the entrance to a site in Peru where anyone seeking entrance to the city has to pass through this hundred-yard-long uphill corridor flanked on both sides by tall walls which would allow armed defenders on top to deny entrance to this city in Peru
A Sixty-Foot high wall all around a city denies inside access to enemy intruders except at the entrance
So what kind of buildings would Nephi have taught his people to build, and would they have been defensive buildings, meant to provide the small community with as much protection as possible against Lamanite aggression, which he feared? As Jacob wrote later, “many means were devised to reclaim and restore the Lamanites to the knowledge of the truth; but it all was vain, for they delighted in wars and bloodshed, and they had an eternal hatred against us, their brethren. And they sought by the power of their arms to destroy us continually” (Jacob 7:24).
Yellow Arrows: Note the steps on the outside of the building, which can only be scaled slowly, and in a single direction
These singular steps are found all over Peru on buildings, walls, and forts
Another method of defensive building found in Andean Peru is the long entrance pathways between tall walls
Still another method of defensive building is outside stairwells, where any enemy intruder would be vulnerably exposed
There seems little question that Nephi would have taught his people how to build in such a way as to protect themselves from the future constant attacks from the Lamanites that Nephi knew would occur. There are many simple manners of building that can protect entrances to buildings, to cities, and within the cities and communities. It would be foolish for any historian, knowing the history of the Nephites and Lamanites, not to expect Nephi to teach his people to build in preparation for such difficult and dangerous conflicts and outright wars. After all, Nephi knew the history of the Lamanite aggression and wars for the Lord gave him a vision of this when he wrote: “And it came to pass that I beheld multitudes gathered together to battle, one against the other; and I beheld wars, and rumors of wars, and great slaughters with the sword among my people, And it came to pass that I beheld many generations pass away, after the manner of wars and contentions in the land; and I beheld many cities, yea, even that I did not number them” (1 Nephi 12:2-3).
