The island has an inner and an outer ring road, the inner being over 1,000 years old and the largest ancient stone structure in the pacific. Built from coral by a chief of uncertain former inhabitants, it had been tar sealed so looks completely unremarkable.
along this road are a few surviving "Maraes", ceremonial stone platforms once used for public meetings and rituals by the Cook Island Maori tribes.
The most impressive one is up in hills on the west side of the island, in a whole ancient village site which dates back 700 years.
and this one points to Aotearoa! It looks like a hand pointing too.
