Overview

Dolmen Juan Rol I is a megalithic tomb in the municipality of Alcántara, Spain, and one of the best-known dolmens of the archaeological group of the Alcántara dolmens. It is built of slate and has a chamber with a long passage; the catalogue gives a typological estimate of 4000 to 3000 BCE for its construction.

Its last recognisable use was in the Early Bronze Age, between 2200 BCE and 1900 BCE, by the Bell Beaker culture.

Description

Sources for this section

The chamber preserves six of its seven original side stones. It has a wide mouth with eleven stones, some bearing cup marks and engravings, which was partly restored in 1997. The dimensions are much larger than those of the adjacent dolmen Maimón II. The chamber has a diameter of 2.3 metres and a height of 1.5 m. The passage is about 5.0 m long and 0.9 m high. The mound, which essentially surrounded the chamber but not the whole of the passage, had a diameter of about 8 m.

Finds

Sources for this section

The chamber has been looted, which explains the condition of some of the orthostats. On the original floor level there were several arrowheads, a large silvered idol with eye holes and strips of triangles as decoration, and some beads. Excavation of the floor also revealed damaged polished axes, cups, beads and arrowheads, which correspond typologically to the motifs engraved on the rock.
