Son Oleza is a prehistoric "Beaker culture" dolmen and associated settlement site on the Spanish island of Mallorca. It is near to the village of Deià on the island's north-west facing coast. The large site, a nearly complete village, has been investigated by Professor Bill Waldren; and in 1998 it was the subject of one of the earliest episodes of archaeological television programme Time Team. Significant features include a dolmen; a water supply system; a maze; and a temple site. The site is believed to have been occupied by several families between circa 2500BC to circa 1300BC.
