A New Megalithic Dolmen from the Balearic Island of Mallorca: Its Radiocarbon Dating amd Artefacts

This paper examines and discusses a ‘dolmenic‘ structure recently discovered on the Spanish Balearic Island of Mallorca. This form of megalithic tomb architecture is the least studied of the many different types of local prehistoric monuments. Only seven dolmens are known in the Balearics (Mallorca and Menorca) and the Pityoussa Group (Ibiza and Formenterra) and only two of these have radiocarbon dating, circa 1750 cal BC to 1550 cal BC. The new structure, the Dolmen of Son Oleza, according to recent findings is the oldest example so far dated. A recent series of nine radiocarbon dates and two earlier analyses cover a period of circa 2200 cal BC to circa 1800 cal BC. The Olezian Dolmen is also the first to have yielded abundant Bell Beaker pottery and associated artefacts. It also reveals geological and architectural characteristics that are unlike other local dolmens, characteristics that by dating and artefact evidence identify it as a possible Balearic prototype. Furthermore, the Olezian Dolmen’s location close to the Chalcolithic Old Settlement of Son Oleza, where identical dates and artefacts have been found, strongly suggests this settlement’s contemporaneity and direct association with the Dolmen. This aspect, along with the other emerging evidence, is completely new to the question of Balearic dolmens, giving us fresh insight as to their chronology, function and socio‐religious importance and significance.
