The Dolmen del Mellizo, also known as Aceña Borrega or Anta de la Marquesa, has a thousand-year history. Although its exact origin is lost in time, it is believed that it was built between the 4th and 3rd millennia BC. This megalith follows the megalithic model known as “anta” in neighboring Portugal. The dolmen chamber is covered by a horizontal slab that protrudes from the roof, and although it is quite worn, the corridor and access to the chamber are still well preserved. In an archaeological excavation carried out in 1985, remains of funerary goods, such as ceramic fragments and arrowheads, were found. The Dolmen del Mellizo is a fascinating place that connects us with the people who built it thousands of years ago. 🌟
