Halekii-Pihana Heiau State Monument is a park containing two important luakini heiau on a high ridge near the mouth of Iao Stream in Wailuku, Maui. Both Halekii and Pihana were associated with important Hawaiian chiefs, have been closely studied by archaeologists, and overlook the fertile Nā Wai Ehā ('Four Waters') region irrigated by the Wailuku, Waikapu, Waihee and Waiehu streams. The heiau complex was added to the National Register of Historic Places on 25 November 1985. Read more on Wikipedia
