Utulongoa'a: From the Ha'amonga trilithon, behind sits the Maka Faakinanga or the leaning rock in which Tu'itatui leant on. It was like his throne. Behind this Throne was the ancient residence of Heketa. Behind this residence is the Utulongoa'a or "noisy cliff". It has been confirmed by Tamale Maka but also Nuku Moimoiangaha that the Utulongoa'a has originated from Niutoua but the name was gifted to Nuku's first son whose mother was Tamale's daughter. Before the King's daughter Fatafehi moved to Lapaha, she stayed in Heketa. But moved because of the noisy cliffs.
