The Kaneohe Ranch Building at Castle Junction, where the Pali Highway (Route 61), Kamehameha Highway (Route 83), and (Route 72) intersect on the windward side of Oʻahu, was built in 1940 to be the headquarters of Kaneohe Ranch, which owned 12,000 acres (49 km2) of surrounding land and played a major role in the history of Kāneʻohe and Kailua. The building is significant both for its association with the Ranch and for its Hawaiian style architecture designed by Albert Ely Ives (1898-1966). Ives' other work on the windward side includes Plantation Estate which is the Winter White House of Barack Obama. The building was added to the National Register of Historic Places on 5 June 1987.
