A significant number of pottery fragments, quite abraded and of small size, appearing to be prehistoric (Bronze Age?) were found.
Pottery and lithic remains were found in previous survey work (FABREGAS-1997), which undoubtedly suggests that this is a prehistoric open-air site (which appears to be confirmed by the presence of other significant archaeological sites in the vicinity, including various petroglyphs and two mounds).
The material appeared in an access track leading to the houses of Trasmañó, in the zone of the recreational area, over an area of 50m. During previous work three closely located spreads were identified, enclosing the picnic area, however in this survey pottery was only found at one of these points.
