was discovered. It had been walled up and yielded artefacts from the time of the Guanches. Since the pyramids lie stratigraphically above the cave, the Guanche finds from between 600 and 1000 AD can only support conclusions on the date of human use of the cave. The above survey indicates that the pyramids themselves cannot be older than the 19th century. Conclusions The archaeologists involved maintain that the creation of the terrace structures followed from the practices of the 19th century rural population, who created these structures while clearing cultivatable land of stones, as they piled the stones into these terrace shapes. Heyerdahl suggested that the structures were not haphazardly piled-up stones. Heyerdahl maintained a belief in the hypothesis that the pyramids were connected with Guanches until his death. The association of the Guanches and the pyramids continues to be elaborated upon both in "Pyramid park" and on its official website. Aparicio and Esteban's theory connects the facts that the pyramids were built in the 19th century with the acknowledgement that they are not simply piles of stones. Ethnographic park Following the completion of the excavations in 1998, the 65,000 m² area surrounding the pyramids was made accessible to the public. Heyerdahl received financial support from his friend the Canarian businessman Fred Olsen, who owns the largest transport company in the Canaries and whose family came to the islands from Norway in the 20th century. An information centre provides visitors with information about Heyerdahl’s research trips and his previous ideas regarding the pyramids. Two pavilions contain exhibits relating to Heyerdahl along with models of his boats; a replica of the Ra II in its original size, amongst others. In spite of the conclusions regarding the age of the pyramids outlined above, Heyerdahl continued to maintain a belief "in a possible relationship between the existence of the pyramids and the pre Hispanic civilisation on Tenerife". The objects found in the Guanche cave are shown in the "museum" in heavily enlarged photos, whilst the imported ceramics from the 19th century are mentioned only briefly on an information board – without illustration.
