Irikaitz archaeological site - host to a 25,000 year-old pendant

In the open air, full of volcanic rocks, difficult to date... the excavations here are unique, according to Alvaro Arrizabalaga and his team at the University of the Basque Country
The recent discovery of a pendant at the Irikaitz archaeological site in Zestoa (in the Basque province of Gipuzkoa) has given rise to intense debate: it may be as old as 25,000 years, which would make it the oldest found to date at open-air excavations throughout the whole of the Iberian Peninsula. This stone is nine centimetres long and has a hole for hanging it from the neck although it would seem that, apart from being adornment, it was used to sharpen tools. The discovery has had great repercussion, but it is not by any means the only one uncovered here by the team led by Alvaro Arrizabalaga.
Irikaitz lies behind the bath spa in Zestoa, on the other side of the river Urola, 14 metres from the river bank. The archaeologist from the University of the Basque Country (UPV/EHU) has been carrying out excavations here summer after summer, together with students and researchers from this and other universities and in cooperation with Aranzadi Science Society. Since 1998 they have uncovered 32 square metres; nothing compared to the eight hectares (at least) that this "gigantic" open-air site covers.
