The Dolmen de la Siureda is located near a road on a marked path, south of Maureillas-las-Illas in the Pyrénées-Orientales department near the border with Spain, in France. Its name comes from the Catalan word for cork oak.
This well-preserved dolmen was built as a collective grave in the late 3rd millennium BCE. It is a rectangular megalithic complex without a corridor, which corresponds in plan and orientation (southeast) to the 148 documented simple dolmens of the region. It was discovered in 1985 in its approximately 10.0 m measuring tumulus, originally set by curbstones, and was the subject of archaeological excavations.
The excavations yielded broken ceramics and fragments of human bones, the dating of which is uncertain, as well as some small objects, including an artificial pearl, a spindle whorl and a fragment of a bronze ring.
