Built in 1926, this 10-story landmark was once the city’s tallest building. In the golden days when all tourists to Hawaii arrived by ship, this pre-WWII waterfront icon – with its four-sided clock tower inscribed with ‘Aloha’ – greeted every visitor. These days, Hawaii Pacific University has bought the Aloha Tower Marketplace and is revitalizing it for retail, dining and student housing. Take the elevator to the top-floor tower observation deck for 360-degree views of Honolulu and the waterfront.
