Petroglyphs of Monte Tetón Curiosity · Tomiño, Baixo Miño, Pontevedra The petroglyphs of monte Tetón are concentrated on two large surfaces of granite rock about 300 metres apart, within the parish of Tebra, in the municipality of Tomiño, although the mountain, almost 500 metres high, is also shared with Tuy and Gondomar. They comprise nearly two hundred carvings from the Chalcolithic and Bronze Age, including concentric circles, cup-marks, quadrangular figures that have been interpreted as a rudimentary cartographic representation, mounting scenes and human figures. Notable is the so-called Real Seco, possibly the largest circular labyrinth in Europe, with eighteen concentric rings up to 3.5 metres across. The complex, known as the Ecoparque Arqueolóxico do Monte Tetón, is covered by a five-kilometre circular route with views over the Val Miñor and the Baixo Miño.
