The Dolmen of Guadalperal, also known as the treasure of Guadalperal and as the Spanish Stonehenge – was discovered in 1926, during a research and excavation campaign led by the German archaeologist Hugo Obermaier between 1925 and 1927. Historians have tried to decipher exactly why and how it came to existence. It has been stated that it could be a solar temple – and has also been used as a burial enclave.
