It might not rival any other “great wall” in the world, but the Great Wall of Kuakini is a lovely place to investigate as part of Hawaii’s history—primarily, the history of invasive animals on the Island. Possibly a territorial boundary meant to keep out unwanted people, it seems more likely the wall was originally constructed to keep dogs and pigs out of the gardens (the Island’s food source). It is believed that Governor, John Adams Kuakini expanded the wall after cattle were introduced to the island. To catch a look at the wall that starts in Kailua-Kona, head to Crossroads Center and Queen Kaahumanu Highway. Then look toward the mountains and you’ll find a bit of Hawaiian history that you can follow in broken sections down the island for nearly six miles.
