If size signified importance, Ahu Vinapu was one of the most
important ahu on Easter Island. The precisely fitted large
basalt cut slabs have perplexed some archaeologists, in
particular Thor Heyerdahl. He points to this Inca-like stone
ahu as a key indicator to a distinct Peruvian influence on the
island. Few experts disagree that the stonework here is more
advanced than that of other ahu on the island. Was this the
result of an Inca influence on the island, or was it due to
years of experience attained by Rapanui stoneworkers? An
average slab here is eight by 5.5 feet (2.5 x 1.7meters) and
weighs seven tons.
