Huilua Fishpond, in Ahupuaa O Kahana State Park on windward Oʻahu, is one of the few surviving ancient Hawaiian fishponds that were still operational well into the 20th century. It was declared a U.S. National Historic Landmark in 1962, shortly after it had been severely damaged by the 1960 tsunami. It was added to the National Register of Historic Places on December 29, 1962. Read more on Wikipedia
