The Kaneohe Ranch Building at Castle Junction, where the Pali Highway (Route 61), Kamehameha Highway (Route 83), and Kalanianaokinaole Highway (Route 72) intersect on the windward side of Ookinaahu, was built in 1940 to be the headquarters of Kaneohe Ranch, which owned 12000 acres of surrounding land and played a major role in the history of Kāneokinaohe and Kailua.
