ʻĀinahau was the royal estate of Princess Victoria Kaʻiulani, heir to the throne of the Kingdom of Hawaiʻi.
ʻĀinahau was located at the ʻili (traditional subdivision) of ʻAuʻaukai, the ahupuaʻa of Waikīkī, on the island of Oʻahu.
In 1872, Scottish businessman Archibald Scott Cleghorn purchased 6 acres at ʻAuʻaukai from two Hawaiians named Maʻaua and Koihala.
[7] ʻĀinahau was initially a country estate while family lived in a mansion on Emma Street in downtown Honolulu, where Kaʻiulani was born.
[8] Her father sold the Emma Street residence to Scots-Irish industrialist James Campbell in 1878 and relocated the family to the country estate.
[9][10][12] A stable was built for several horses, including quarters for Kaʻiulani's prized pony named Fairy.
[14] The site was later developed by the owners of the Moana Hotel, located across Kalākaua Avenue, which had been built towards the end of Kaʻiulani's life.
