The Dolmen de Toriñuelo circular chamber tomb

The Dolmen de Toriñuelo is a circular chamber tomb, located on a farmland two to three kilometres from Jerez de los Caballeros, in the province of Badajoz, in the community of Extremadura. It belongs to the Calcolithic period. This monument was declared a national monument in 1926 and took on public ownership in 2009.

It is oriented in an east-west direction, with a long corridor of access of about 25 metres. The chamber, slightly oval, is delimited by orthostats. One of these orthostats does not remain in this dolmen. The majority are made of granite and two of them of pizarra. The structure is an artificial hill, raised by the superposition of tongadas or layers of clay and stones, all very compacted layer by layer.

The dolmen is covered with a false dome and a Tholoi, which is a lintelled corridor - a horizontal structural element that spans a space between two supports. This is a significant construction feature, alongside the dimensions of the lintelled corridor and the existence of a lateral chamber.
