The only town in Rapa Nui is Hanga Roa. It sits right next to the ocean and sculptures line the coast.
I found these signs next to the sculptures. From what I can tell they are telling us who sponsored the sculpture. They are in the shape that is the local symbol of Rapa Nui. It looks like a boat with two heads and symbolizes authority.
Iorana is the word for ‘hello’ and ‘ goodbye’.
