1. The Great Wall of Kuakini (foreground) came first. John Adams Kuakini, Royal Governor of Hawaii Island from 1820-1844, is responsible for the building of this "series of low walls that were orignally used as Ahupuaʻa (land division) barriers for pigs, because the cattle left behind by George Vancouver were wandering through the village of Kailua." (Wikipedia).
2. The Wall of Borders (middle) came next. This photo was taken from the Borders Books parking lot.
3. The Wall of Lowe's of Kailua-Kona (top) was last. When it was being built, there were jokes about it being the Lowe's heiau. Now, they're all a part of the landscape but the Great Wall of Kuakini is a registered historic site.
My favorite though, is the partially destroyed stone wall of silent character. More on Kuakini by Robert Oakes.
