As part of the increase in the defensive capabilities of the eastern line, a city is begun, and named after Moroni, the man behind these building programs. This will be short-lived city. It is placed by the east sea, and as Sorenson notes, was the only city to receive this designation of being “by the sea” (John L. Sorenson. The Geography of Book of Mormon Events. FARMS, 1990, p. 276). This location “by the sea” is significant for the future of the city, for it will sink into the ocean in a generation (3 Nephi 9:4).
