Onenoa is a village located in the northeast of Tutuila Island in Vaifanua County in the Eastern District.
Historically, such fortifications were built to protect against Tongan marauders or rival Samoan raiding parties during periods of internal conflict.
[5] On a coastal bluff above Onenoa lies the only significant area of Kula (tula) fernland in American Sāmoa, covering slightly more than one hectare.
A smaller patch of similar vegetation exists on a coastal bluff at Atauloma on the island's southwest coast.
[7] On March 3, 1996, it was reported in Samoa News that the Onenoa Village Council had passed a new set of ‘Sa’ laws.
