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