ʻĀinahau
Honolulu County, United States
Āinahau was the royal estate of Princess Victoria Kaiulani, heir to the throne of the Kingdom of Hawaii. The estate included a 19th-century bungalow and a larger main house was built in 1897 to celebrate Kaiulani's return from Europe. Āinahau was destroyed in 1921, and the site later became the Sheraton Princess Kaiulani Hotel.
