In old times, it was most likely a holly oak woods and bushes area. The nearer rock is gneiss, stale and quartz outcrop. It is located at 500m high over the sea, on a dominant plateau.
It is near the Pallera dolmen and near Roca Galera. There is an important group of carvings of cup marks and grooves that form motifs of wheels with inner crosses in both sides of the creek of la Vall de Santa Creu. There is a series of stones with cup marks. There has never been any archaeological excavation. Architecturally, it is formed by a semiartificial circular chamber with a narrow corridor. In old times all of it was covered by a tumulus, that some rests have remained, and it should have measured 8 or 9 meter diameter.
It is dated in the first half of III millennia B.C. (between the third and fourth period of the passage tombs in l’Alt Empordà – Rosselló)
It is discovered by Josep Antoni de Nouvilas at the late XIX century. The Geseart publishes about it in their book about megalithic monuments in Alt Empordà, in 1988. Tarrús and Chinchilla mention it in 1992.
