Dolmen de Guadalperal Monument · Peraleda de la Mata, Campo Arañuelo, Cáceres Megalithic monument from between the fifth and third millennia BC, with more than 140 granite slabs, a funerary chamber about 5 m in diameter, and a passage nearly 10 m long, popularly known as the 'Spanish Stonehenge'. It remained visible for about forty years after its discovery until the waters of the Valdecañas reservoir covered it in 1963; since then it has reappeared intermittently during the most severe droughts, as in July 2021 and the summer of 2022. 1963 (quedó sumergido); emersiones documentadas en 2021 y 2022 Photo: Pleonr (CC BY-SA 4.0) What to see and do in Peraleda de la Mata
