From 1988 to 1993, Thor Heyerdahl administered archaeological excavations of the “La Raya” pyramid complex just outside Túcume in northern Peru. During the period of excavations this was the largest archaeological project in the world.
The ruined city outside Túcume was shown to have been built about 1100 AD.The area houses 26 pyramid-like adobe structures and a range of other ceremonial sites
graves were uncovered with fantastic burial artefacts, including beautiful silver statuettes and featherwork textiles.
They also found evidence that the people of Túcume had included experienced travellers among their number. Shells from Ecuador and Panama and lapis lazuli from Chile were found.
Archaeologist Alfredo Narváez excavated a well-preserved adobe wall decorated with a mystical scene in high relief that shows birdmen onboard two large reed vessels surrounded by fish, seabirds and a symbolic motif known from pre-Incan art, so-called anthropomorphic waves. Depictions of birdmen that are similar in style to the ones in Túcume are found on Easter Island.They also found a preserved rudder blade from a small balsa raft and a jar of black ceramic that showed two men onboard a reed boat. All of this supported the supposition that the people in these regions were seafarers in pre-Columbian times.
