Hanaiakamalama, the name of the country estate of Kamehameha IV and Queen Emma, was once in the secluded uplands of Nuuanu Valley. These days it’s adjacent to a six-lane highway full of speeding cars. This simple, seven-room New England–style house, built in 1848 and restored by the Daughters of Hawaii, is worth an hour of your time to see the interesting blend of Victorian furniture and hallmarks of Hawaiian royalty, including feather cloaks and kahili, the feathered standards that mark the presence of alii (royalty). Other royal treasures include a canoe-shaped cradle for Queen Emma’s baby, Prince Albert, who died at the age of 4. (Kauai’s ritzy Princeville Resort is named for the little prince.)
