The dolmen Losa de la Mora or of Rodellar is a well-preserved dolmen located in Rodellar, in the municipality of Bierge, in the Sierra de Guara (Huesca, Spain). It is at an altitude of 1020 masl.[1]
It dates from Neolithic, from circa 3000 BC. It consists of three orthostats covered by a large slab, which gives the dolmen its name. The rocks that form it come from the Tozal de Llastras, a place located about 500 m. far. The dolmen is surrounded by numerous stones belonging to the mound that covered it, with a diameter of dispersion of about 12 meters.[2] It was excavated by the archaeologist Martín Almagro Basch in 1935 and 1936, finding stone axes, flint tools and skeletal remains of various individuals.
The dolmen is on a mountain pass next to a signposted path that starts from Rodellar and leads to the uninhabited towns of Otín and Nasarre.[3]
