Dolmen de Soto

The Dolmen de Soto is a Neolithic subterranean structure in Trigueros, Andalucía, Spain. It is estimated it was built between 4,500 and 5,000 years ago and is one of about 200 neolithic ritual-burial sites in the province of Huelva.The site was discovered by Armando de Soto Morillas, as he wanted to build a new house in 1922 on his estate, La lobita. The same year excavation works were initiated on the burial site and by 1924 the German archaeologist Hugo Obermaier was asked to perform some research by the Duke of Alba, Jacobo Fitz-James Stuart. Obermaier discovered eight buried bodies in a fetal position accompanied with artifacts following which Obermaier published a book describing the results of the excavation and the characteristics of the funerary site. In 1931 it was declared a National Monument of Spain, but it stayed a private property until 1987, when it was included within the jurisdiction of the Spanish Ministry of Culture.
