Arorae is the southernmost of the Gilbert Islands. Although this island is called atoll, it is not the classical ringshaped island with a lagoon in the middle. This island is 9 km long, it’s area is 9.5 km². The nearest landmass is the small Tamana Island located 88 km to the northwest.
In the northern tip of the island is located a group of standing stones – flat slabs of coral stone, set on the rim and fastened with stone pavement around them.
Captain E.V.Ward sketched the stones in 1946 (2.). There were 14 stones in total.
The largest was entrance stone, others were stones used for orientation. In the 1940s 11 stones were in their original locations. In 1957 there were found less – 8.
Stone slabs are approximately 1.5 -1.2 m wide and tall and some 15 cm thick.
Stones are located among the trees and the sea is not visible from here. But in earlier times this could be different – the island has extended northwards over the last centuries.
Signs to the nearby islands
It can said with certainty that ancient Polynesians erected these stones as a signs pointing towards the nearest islands. Locals now call them Te Atibu-ni-Borau – the stones for voyages.
It is considered that in the afternoon people went with canoe near these stones and were guided by some helpers to take the exact position pointing away from Arorae towards the desired destination. Soon the stars appeared and seafarers could orientate by them. After 12 hours, when the sun went up, they were near the neighboring islands.
A local man in 1946 told to Captain Ward, that his father knew how to use them. Even more – another informant told that the stones were erected in their father’s lifetime – e.g. in the late 19th century. Other stories though mention that these stones were standing well before the coming of Europeans.
Only on Butaritari Island in the northern part of Gilbert Islands is known a similar monument.
Where do you want to go?
The stones in Arorae point to the following islands:
- A pair of stone plates points to the nearest island – the 88 km far Tamana Island.
- One (possibly earlier there were two) stones point to the open sea. May be they show the way to the 720 km far Banaba?
- One stone points to the 120 km far Nikunau.
- Next to it stands one, which points to the 140 km far Beru.
- One (may be there were two in the past) stone points towards Onotoa, 137 km far.
- Two stones point seem to point again towards the 88 km far Tamana Island. Ward mentions the 1250 km far Orona in opposite direction but this seems way too far.
- A pair of stones points towards the south-west, no land is there for more than 1200 km.
Limits of the system
This certainly was not an exact and safe navigational system. For example – stones are shifted by 5° from the exact position – most likely to decrease the mistake created by the equatorial current.
If the current was faster of slower or there was a wind, the canoes would sheer away and get lost in the Pacific. The distance of 80 – 140 km might be the maximum where such navigational aid can be of any assistance.
It is also not clear how the seafarers found a way home.

|Address:||Australia and Oceania, Micronesia, Kiribati, Gilbert Islands, northern tip of Arorae Atoll|
|Alternate name:||Te Atibu-ni-Borau, the compass stones of Arorae. The island has several names – Arorai, Arurai, Hope, Hurd.|
|Age:||Around 1000 – 1500 AD|
The area of Kiribati exceeds the area of United States. But most of it is taken by ocean, the land area is only 811 km². This is an exciting land of extremes, with local people living in extreme powerty and at the same time leading such way of life which is mildly named “non-consumerist” way of life. In reality it means – most people in Kiribati don’t care about “our” rules of economics, which keep the Western society in tight iron grip.
One of the most fascinating groups of archaeological monuments are prehistoric structures made of stones – megaliths. Through the ages, people have loved to strain their minds to find a sensible explanation to the many riddles posed by megaliths.
Even today, we can admit with some pleasure, there are thousands of mysteries left for us.
Explores new evidence of the presence of ancient astronaut gods as revealed in the unusual artifacts and sites discovered on the remote Kiribati Islands of the South Pacific.
In the many centuries preceding Western contact, a richly diverse and innovative architectural tradition reached maturity in the western Pacific. Prehistoric Architecture in Micronesia, the first modern study of this remarkable work, reveals that there is no such thing as primitive architecture but only primitive means.
